Electrical Switchgear
1.1 Functions performed by electrical
switchgear
National and international standards define the method for making electrical
distribution circuits as well as the purpose and functions of switchgear.
There are three main functions, namely:
■ circuit protection takes three main fault types into account:
❏ overloads,
❏ short-circuits,
both of which adversely affect the lifetime of cables and loads,
❏ insulation faults, harmful for persons and equipment.
■ isolation is used to separate a circuit or a device from the remainder of the
installation to allow 100% safe operation,
■ control allows the user to take voluntary action on installation operation:
❏ when such action takes place in normal operating conditions (on load, with no
overcurrent) in order to energise or de-energise all or part of the installation,
control is said to be “functional”,
❏ when such action is essential (whatever the load condition of the installation) in
order to immediately de-energise all or part of the installation, control is said to be
of the “emergency stop” kind.
Three main functions:
■ protection,
■ isolation,
■ control,
of electrical circuits.
The switch is used for:
■ control,
■ often isolation.
For protection it must be
combined with:
■ a circuit-breaker,
■ fuses,
■ a residual current device
(if necessary).

1.2 Functions performed by the switch
The switch is mainly:
■ a control device:
❏ control is normally manual,
❏ it can be electrical on opening (we then talk of a switch with automatic opening),
❏ able to break and make a circuit on-load.
It does not need any energy to remain open or closed (2 stable positions).
■ for safety reasons, the switch is often equipped with a suitability for isolation
function,
■ the switch must always be used in coordination with an overload and shortcircuit protection device.

2.1.1 Switch applications
Switches are characterised by
market values taking into account:
■ 6 applications,
■ the installation method,
■ user habits such as type of
isolation: with visible isolation or
positive break indication.
These market values induce
choices of technology and
reference standards.

Figure 1b: Functions table
According to its position in the installation, its application and assembly in the
installation system, the switch must meet certain market values in terms of:
■ adaptability to installation systems,
■ standard requirements (installation).
Market values must also be considered, relating to habits such as:
■ operating handle types (front, side, etc.),
■ accessory level,
■ assembly habits,
■ visible isolation,
or other habits linked to operator safety such as:
■ rapid identification of the isolation device in the middle of other devices,
■ robustness appearance of switchgear performing the on-load circuit control and
isolation function,
■ etc.
The summary of applications and market values leads us to consider the
functionalities listed in the table opposite.
(1) As from the beginning of 1998 IEC standards have received new numbering in IEC 60xxx.
However their content remains the same.

In short
2.2 Main functions
2.2.1 Functions applicable to all switches
Suitability for isolation is an
important function that the switch
must possess.
2.2.1.1 Standards
To satisfy the previous applications, two technologies are available:
■ industrial type switches for industrial and tertiary applications,
■ industrial type switches for domestic applications.
On-load breaking is a natural
function of the switch.
The reference standards for switches are:
■ in industry and the tertiary sector:
❏ standards IEC 60947-1 and IEC 60947-3 / European standards EN 60947-1 and
EN 60947-3.
■ in domestic applications:
❏ standard IEC 60669-1.
The additional safety, emergency
stop and earth leakage protection
functions are accessible to
switches.
2.2.1.2 Isolation
Operation of an electrical installation requires the possibility of working with power
off on all or part of this installation in order to perform maintenance and servicing
or to make modifications.
■ Padlocking a feeder
Installation standards define the compulsory feeder padlocking operations to
guarantee safety of the operations. Switchgear separating the relevant feeder
must be recognised as “suitable for isolation” and possess a locking system in the
"open" position.
■ Position of isolation in the installation
An isolation device must be installed at the origin of each circuit distribution point in
order to ensure optimum continuity of supply ("incoming end" of the enclosure/
subdistribution cubicle).
2.2.1.3 Switch/disconnector
E58482
Some switches perform this function in addition to their circuit control function.
They are then switches/disconnectors whose symbol, shown opposite, must be
clearly shown on the front face of the device installed.

Figure 2: Marking a switch suitable for isolation
The “isolation” function is performed in 2 ways:
■ visible isolation,
■ positive break indication.
The industrial switch construction standard IEC 60947-3 defines the rules and the
tests to be performed to guarantee this function (see section 3.3.4).
6
■ Suitability for isolation
Isolation is explicitly defined and recognised by standard IEC IEC 60947-1-3 for
industrial type switches/disconnectors. A switch/disconnector complying with this
standard for the isolation function unconditionally meets the additional tests and
requirements of the installation standards.
■ Implementation and utilisation precautions
Switchgear suitable for isolation must:
❏ have multi-pole breaking, i.e. the live conductors, including the neutral
(except for the PEN conductor that must never be broken) must be able to be
simultaneously broken,
❏ be lockable in the “open” position in order to avoid all risk of accidental
reclosing, essential on industrial type devices,
❏ be able to meet overvoltage withstand conditions.
Before working on the part of the installation downstream of a switch/
disconnector, the user must:
❏ open the switch,
❏ then, in all cases, compulsorily check absence of power,
(if the switch has visible isolation, see section 334 of the Standards - suitability for
isolation),
❏ check contact opening.
■ Choice of isolation
Choice of isolation mode depends on:
❏ market habits,
❏ switch rating.
The manufacturer must:
❏ propose safe, reliable solutions guaranteeing customer safety,
❏ ensure the best possible value (quality and performance) for money.
■ Comparison of the 2 isolation types

2.2.1.4 On-load breaking
The operator must be able to safely and easily put his electrical installation out of
operation regardless of load conditions. For switches, on-load breaking is
essential and tests are required by standard IEC 60947-3. Switch electrical
performance depends on its position in electrical distribution:
Type of current to be controlled:
The utilization categories defined by standard IEC 60947-3 specify the various
requirements to be met according to the circuits to be controlled.
■ When the switch is installed at a high upstream level in LV distribution, the loads
supplied are numerous and mixed: the current to be controlled is of the inductive
type. Utilization category AC22 is recommended for this type of switch.
■ When the switch is installed at the incoming end of the distribution enclosure (or
cubicle), the loads supplied may be not very inductive (power supply, lighting,
convector, etc.). Utilization category AC21 is sufficient for this type of application.
However, the same type of enclosure can be used to supply a mixed installation
with motors: utilization category AC22 is then necessary. To simplify the choice
and guarantee proper operation, whatever application is performed, utilization
category AC22 is always recommended at this level.
■ When the switch is placed directly on a motor feeder and used as a control
device, it must meet:
❏ a utilization category AC23, if control is occasional (normal control by a
contactor),
❏ a specific utilization category AC3, if the switch is the main motor start-up and
stopping device.

E62416
Number of operation
The nearer the switch to the loads, the greater the number of operations. A suffix
attached to the utilization category -A (frequent operations) or B (infrequent
operations) defines operation frequency. In electrical distribution, the number of
operations to be performed is never very great (a few thousand).
2.2.1.5 Additional safety functions
Additional functions are often requested for switches ensuring local and
subdistribution isolation.
MN release
■ The “emergency stop” control
This is performed in 2 ways:
❏ remotely by an emergency pushbutton either by a contactor or by a switch with
automatic opening. The controlled switch is installed in a switchboard or enclosure
in standard manner. It is necessarily equipped with an automatic tripping device
and, in many cases, with auxiliary indicating contacts,
❏ directly by means of a switch. Safety regulations and/or installation standards
specify that in this case the device must be easy to identify and access.
Identification is based on choice of colours:
- operating device (red handle),
- front face (yellow front plate).
Pushbutton emergency stop
052967
■ Insulation fault protection
Insulation fault protection can be provided by a Residual Current Device (RCD)
associated with or incorporated into a switch depending on the application in
question.
❏ Subdistribution switchboard isolation switch
The RCD is associated with a controlled switch (with automatic tripping).
The RCD provides protection of persons (indirect contacts) and protection against
fire. It must be selective with the downstream RCDs.
❏ Final distribution switchboard and enclosure isolation switch
The RCD is built into the switch and is normally dedicated to a single protection
function: persons (direct contact), fire, etc.

NB: In all cases, the chosen switchgear will be able to break overloads and
abnormal currents, thus excluding from this function devices only of the
disconnector type.
In short
2.2.2 Specific functions
2.2.2.1 The coupling function
Depending on the position of the switch in the LV installation and on the operator’s
specific needs, the coupling function can be automatic or manual.
E62417
Switches can be used to perform:
■ coupling functions,
■ local isolation and disconnection
functions.
In this case they have specific
features.

Automatic coupling
■ This function is normally built into the “source changeover” function (e.g. 2
sources and 1 coupling). Should one of the sources fail, the loads are
automatically coupled to the second source. This is performed at the supply end of
LV distribution.
■ This function is mainly found in the main LV switchboard or the incomers of the
subdistribution switchboard (see fig. 4a and 4b).
■ Specific features
The switches are located near the sources: the lsc are high (from 30 to 80 kA).
Time discrimination is often used: the fault currents are not limited. This results in a
need for high withstand performance in short-circuit conditions:
❏ thermal stress withstand: the main LV switchboard specifications may impose a
withstand of 80 kA - 1s for a busbar in a 3000A main LV switchboard,
❏ making capacity lcm: the coupling may close and make a high short-circuit
current.
Switchgear has a motor mechanism. An electrical and mechanical interlocking with
the other source changeover switch components is necessary.
NB: When this function is combined with the automatic source changeover function, it can be
performed by circuit-breakers with only instantaneous protection to limit stresses on the
installation in event of closing on a short-circuit.
Manual coupling
■ This function is normally used to couple:
❑ a set of loads on an emergency network,
❑ a set of loads on a moving generator.
The switch manually and locally performs the transfer to the emergency
replacement network. This load transfer is occasional and programmed.
■ This function is mainly found on the incomers and feeders of the subdistribution
switchboards (see fig. 4c).
■ Features: switches are at the heart of distribution:
❑ they are normally protected by limiting type circuit-breakers,
❑ occasional, voluntary coupling considerably limits the risk of anomalies
(particularly during coupling).
The switch has standard features and is of the manual type. Device interlocking is
necessary.

2.2.2.2. The motor "isolation" function
When a “motor circuit” is supplied and protected from a centralised power supply
to guarantee safety and simplify maintenance, a local control and isolation device
is frequently required. These functions are performed by a separate device known
as a “local isolation enclosure” containing an on-load breaking switch.
Switch features
n In most cases, motor control is performed by a contactor. The switch only
performs “occasional” control of the motor: utilization category is AC23.
n For some small motors (< 18.5 kW), the switch may be considered to be the main
control device of the motor: utilisation category is AC3.

In short
Switch Standards
The switch must comply with:
■ standard IEC 60669-1 for
domestic applications,
■ standards IEC 60947-1 and
60947-3 for tertiary and industrial
applications.
These standards specify the main
technical data of the switches: rated
currents and voltages, utilisation
category, etc.
Standard IEC 60947-3 completely
defines the suitability for isolation
of industrial switches.
3.1 General
Low Voltage switchgear standards lay down all the general common and specific
requirements and measures. They particularly specify:
■ equipment definitions,
■ its technical data,
■ information on the equipment,
■ normal operating, assembly and transportation conditions,
■ construction and operating specifications,
■ tests.
The switches comply with standards (1):
■ IEC 60947-1 (general requirements) and IEC 60947-3 (specific switch
requirements) for industrial switches,
■ IEC 60699-1 for domestic switches.
3.2 Normal standard values for domestic
switches (IEC 60669-1)
■ Rated voltages and currents
❏ rated voltage: preferably 130 V, 230 V, 250 V, 277 V, 400 V, 415 V, 440 V,
❏ rated current: preferably 6 A, 10 A, 16 A, 20 A, 25 A, 32 A, 40 A, 63 A.
■ Breaking capacity
The standard stipulates a “suitable breaking capacity”. This conformity is verified
by a test depending on rated voltage and current as given below.

■ Suitability for isolation
Standard IEC 60699-1 does not give any recommendations regarding visible
isolation or positive break indication.
The tests required are also less demanding than for industrial switches:
❏ for dielectric testing, a 50/60 Hz voltage of between 2000 V and 4000 V
(depending on application point) is applied for 1 minute. A check is run to ensure
that the insulation resistor retains a minimum value (2 to 5 MΩ according to the
test),
❏ no impulse wave testing required.
Moreover, the domestic switch test conditions match class AC22, see section 3.3.3.
(1) IEC standards were renumbered in IEC 60xxx at the beginning of 1998, but their content
remains the same.
12
3.3. Normal standard values of industrial
switches (IEC 60947-3)
The specifications and tests relating to each switchgear type include 2
documents:
■ the general requirements of standard IEC 60947-1,
■ the specific standard for the equipment considered.
For switches, standard IEC 60947-3 completes, amends or replaces the
specifications of the general requirements of standard IEC 60947-1.
E58428
3.3.1 The definitions
Figure 6: Switch
The standard gives specific definitions, including those for:
■ The switch: a mechanical connection device:
❏ able to make, withstand and break currents in normal conditions, including
overloads,
❏ able to withstand currents in abnormal conditions, such as short-circuits, for a
specified period of time,
❏ able to break on no-load (with no load downstream).
E58429
■ The disconnector: a mechanical connection device:
❏ meeting the specifications for the isolation function in the opening position,
❏ able to withstand currents in normal conditions as well as currents in abnormal
conditions, such as short-circuits, for a specified period of time.
■ The switch/disconnector:
❏ a switch meeting the specifications for the isolation function in the opening
position.
E58427
Figure 7: Disconnector
3.3.2 Standard usage values
Figure 5: Switch/disconnector
■ Conventional thermal current, lth (A)
The maximum current that a switch can permanently convey without excessive
temperature rise. This value is associated with a utilisation temperature given by
the manufacturer:
e.g. lth = 400 A, lth = 25 A at 40°C.
Normally lth = lu (lu = unbroken current). lth actually corresponds to the switch
rating.
■ Short-circuit making capacity, lcm (A peak)
The short-circuit current value that the switch can make, on closing on a shortcircuit, without being damaged.
■ Electrodynamic withstand (A peak)
The maximum current, in peak value, that the main contacts can withstand without
repulsion.
e.g. 10 kA peak.
This value must be taken into account for protection by circuit-breaker or fuse.
This value is not a standard one. When it is not declared, it corresponds to the
short-circuit making capacity (lcm).
■ Thermal withstand, lcw (A rms-s or in A2s)
The overcurrent that the switch can withstand for a given time without being
damaged.
e.g. lcw = 3 kA rms for 3 seconds.
■ Rated operational current, le (A)
The switch’s utilisation current, depending on the application (resistive or inductive
circuit: see below section 3.3.3. “Utilization categories”).
13
3.3.3 Utilization categories
The standard identifies three types of utilization categories:
■ AC21: resistive loads,
■ AC22: mixed loads,
■ AC23: inductive loads,
■ AC3: direct control of a single motor.
As regards DC current devices, categories are respectively: DC20, DC21…,
DC3, etc.
A letter, A or B, is associated with each ACxy category, according to whether or
not the device is designed for frequent switching operations:
■ A: frequent operations: from 2 000 to 10 000 operations (mechanical and
electrical) as per rating,
■ B: non frequent operations: from 400 to 2 000 operations (mechanical and
electrical) as per rating.

3.3.3.2 Example
A switch with a rating of 125A and category AC23 must be able to:
■ make a current of 10 ln (1 250 A) with a cos ϕ of 0.35,
■ break a current of 8 ln (1 000 A) with a cos ϕ of 0.35.
3.3.4 Suitability for isolation
Standard IEC 60947-1 clearly defines the general rules governing suitability for
isolation.
Standard IEC 60947-3 specifies the requirements to be respected to perform the
switch isolation function.
These standards are based on:
■ the construction rules,
■ the tests to be performed.
3.3.4.1 The construction rules
The construction rules stipulate (among others):
■ the clearances and the distances between open contacts (> 1mm/kV) or, if this
is not the case, verification by sampling device withstand to voltage impulses,
■ presence of a device indicating the real position of the contacts (operating
handle if its position is representative of that of all the contacts),
■ when an interlocking position is provided, the setting in the “interlocked” position
must be possible only if the contacts are “open”.
14
3.3.4.2 Visible isolation or isolation with positive break
indication
Isolation can be achieved in two ways:
■ visible isolation, in which the operator directly views, through a transparent
screen, the physical separation of the main contacts,
■ isolation with positive break indication: in this case a mechanical device
guarantees that the position of the main contacts reflects the position of the
handle. In other words, the switch handle must only indicate the open position if
the main contacts are effectively separated.
The standard defines for this a mechanical verification test (the “welded contact”
test).
The standard specifies that a switch suitable for isolation must be equipped with
padlocking of the isolated status.
The “interlocked” position must only be possible when contacts are “open”.
3.3.4.3 Tests to be performed
E58426
E58425
Three specific tests must be performed:
■ Impulse wave withstand (Uimp)(1)
Conditions are those defined by standard IEC 60947-1, i.e.:
❏ either a distance between contacts greater than that given for a nonhomogeneous field,
❏ or the withstand to an impulse wave whose level is defined according to the
value Uimp declared by the manufacturer.
The impulse wave withstand tests (1.2/50 µs wave), defined in IEC 60947-1, of a
value Uimp variable according to the place of installation, are representative of
lightning and switching overvoltages. They must be performed by the
manufacturer if he announces a value for Uimp.

(1) All electrical installations can be subjected to occasional overvoltages with many causes
such as:
■ lightning overvoltages,
■ switching overvoltages,
■ overvoltages due to a fault,
■ overvoltages further to an MV/LV flashover.
The study of these overvoltages (origin, value, location, etc.) and the rules to be applied for
protection, form the elements of insulation coordination. These studies recorded in standard
documents define the voltage level Uimp to be applied to a device to ensure that it guarantees
the safety of the de-energised part.
15
❏ Voltage impulse withstand level
Network voltage and the position of the switchgear in the electrical network
determine the overvoltage levels to which electrical switchgear risk being
subjected (table H1 of standard IEC 60947-1).

- suitability for operation in service (mechanical and electrical durability),
- making and breaking capacities.
E58424
■ Mechanical test
“Verification of the robustness mechanism of the control device and of the position
indication” or “welded contact tests”.
This test is performed for devices declared suitable for isolation with positive
break indication.
With the contacts held in the closed position, the handle is subjected to a force F
equal to 3 times the effort required to operate it (with a minimum value at 150 N and
a maximum value at 400 N) for 10 seconds.
While the force is being exerted, interlocking of the switching device must not be
possible.
After testing, when the handle is released, indication of the “open” position must
not be inexact.

3.3.5. Electromagnetic Compatibility (EMC)
■ Immunity:
The mechanical connection devices are not affected by electromagnetic
disturbances.
No tests are required.
■ Emission:
Disturbances can only be generated during electrical switching operations and are
limited to switching overvoltages of a lower level than shock resistance.
Consequently, emission specifications are considered to be satisfactory and no
tests are required.
3.3.6. Test Sequences
Besides the specific isolation aspect, standard IEC 60947-3 lays down sequence
operating tests.
Each sequence includes several tests and is used to verify part of the device
characteristics.
These operating tests are summarised in the table below.
The operating mode of these tests results in consideration of real operating
conditions, thus guaranteeing users that products really are suitable for operating
conditions.

The Schneider Electric
choice
Schneider Electric offers switch ranges of the Merlin Gerin and Telemecanique
brands. These devices cover all the requirements of Low Voltage electrical power
distribution, namely:
■ industrial switch/disconnector ranges meeting standard IEC 60947-1-3 from 12
to 6 300 A,
■ domestic switch/disconnector ranges meeting standard IEC 60669 from 1 to 125
A and in some cases standard IEC 60947-3,
■ switch/disconnector ranges for motor feeders meeting standard IEC 60947-1-3
from 12 to 175 A.
The ranges of switches proposed:
■ are perfectly coordinated with the Schneider Electric protection devices,
■ fit perfectly into the Schneider installation systems, thus optimising their
implementation,
■ are suitable for isolation.
18
In short
4.1 The Schneider Electric technical
choices
4.1.1 Isolation
In its capacity as a manufacturer,
Schneider Electric has chosen to
completely guarantee operator
safety by necessarily offering
switches satisfying the isolation
mode with positive break indication.
Circuit isolation is a function that must be performed in complete safety.
4.1.1.1 Choice of isolation
For those ranges of switches, Schneider Electric has chosen :
the isolation mode with positive contact indication.
To ensure maximum user safety, the isolation mode with positive contact indication
is the most effective solution from a technical standpoint. The position of the
control device guarantees absence of voltage.
4.1.1.2 Positive contact indication
■ Advantages
For devices with positive contact indication, the position of the control device in the
rest position reflects contact opening.
This function is:
❏ guaranteed by the manufacturer (inherent safety guarantee) and is no longer
the operator’s responsibility,
❏ possible whatever kind of accessories are used: extended handle, handle
through door, etc.
■ Implementation requirements
There are no special requirements linked to use of this technology type. With
positive contact indication, the position of the control device must reflect contact
position by means of a “reliable and tamper-proof” mechanical device, the tests for
which are defined by standards.
Consequently, there is no longer any risk of incorrect judgement by the user, as is
the case for switches with visible isolation only.
4.1.1.3 Visible isolation
Visible isolation is sometimes imposed by installation standards (in France, for
example, standards NF-C 13-100 and NF C 14-100 concerning connection).
■ Advantages
Visible isolation appears to offer operators additional safety as they can observe
contact opening.
■ Implementation requirements
As indicated page 9, before working on the installation part downstream of a
switch/disconnector, the user must:
❏ open the switch,
❏ then, in all cases, check absence of voltage. If the switch has visible isolation
(refer to “Standards - suitability for isolation”) the user must :
❏ check contact opening.
Isolation is in actual fact guaranteed by the operator who has validated
contact opening.
Visibility is perfect when the device is new and mounted in an enclosure without a
door. For visibility to be guaranteed over time, a certain number of design
requirements are necessary.
19
The following table lists the phenomena that might interfere with contact position
interpretation:
Application case
Device status after electrical switching
operations
Use of switch with an extended or
side handle in an enclosure with
plain door
Use of switch with an extended or
side handle in an enclosure with
transparent door
Observations
Current breaking pollutes the aperture
and visible isolation becomes
questionable and even invisible.
For guaranteed isolation, it is necessary
to open the enclosure door to check that
contacts are really separated.
Otherwise, there is a risk op padlocking
a device that is not open.
There is a real danger for the user (1).
It all depends on equipment assembly
and place of installation. The result may
may be very similar to the above case.
Table J
(1) The standard does not impose mechanical tests on the interlocking linking the position of the
handle to that of the contacts for devices with visible isolation.
4.1.1.4 Schneider “visible isolation” technology
Schneider Electric has developed a specific range of switches (INV range). For
these switches with visible isolation, Schneider gives priority to maximum
safety:
■ isolation with positive contact indication is guaranteed in addition to visible
isolation,
■ the main switch contacts are placed at the rear of the device. Consequently, the
range is optimised to offer the best compromise between user safety and visibility
of main contacts: class 2 classification of devices is maintained,
■ the transparent cover allowing contact visibility is guaranteed for 200 electrical
switching operations. Beyond this number, its interchangeability will allow
maintained visibility,
■ isolation with positive break indication is maintained.
Schneider has chosen to assume responsibility for the isolation
function.

4.1.2 Front face class II
casing
class II
front face
class II
The Schneider Electric devices are front face Class II: this Class is maintained
when the device is equipped with direct control via a metal front plate (case of a
Devices must be designed according to specific building considerations:
■ case of devices with positive break indication. There are two insulating
enclosures (double insulation front face): safety is maximum,
■ case of devices with visible isolation. Class II is obtained by demanding criteria
to be respected (for devices with an Ui 750/800 V):
❏ impulse wave withstand at 14.7 kV,
❏ backing up of creepage distances.
These criteria have a certain effect on device construction, as devices with visible
isolation cannot have a double insulating barrier:
- the main contacts are located at the rear of the switch to ensure maximum
safety,
- visibility of main contacts is thus slightly less good, but user safety is maximum.
052967
Figure 10: Class II diagram
4.1.3 “Emergency stop” control
■ By manual control
The INS, INV and VARIO switch ranges, are also available in the “emergency stop
switch” version, conform to VDE recommendations.
These switches can be identified by their colours: red handle, yellow case front
face.
Switch characteristics and performance are identical to those of standard
switches.
■ By automatic control
The switch is standard and trip-free. To perform a safety function, tripping will use
an MN coil. This coil will be de-activated by the emergency stop normally closed
contact.

4.1.4 The switch is an environmentally-friendly
product
Anxious to protect the environment, Schneider Electric takes three types of action:
■ first, it produces products of a modular design and thus completely separable
into single-material components,
■ second, it uses:
❏ materials containing no harmful substances, in particular no cadmium, mercury
or asbestos,
❏ carefully selected thermoplastics for the moulded parts of the device. Elimination
of these materials, even by incineration, does not give off polluting substances.
■ third, it implements non-polluting manufacturing processes: ISO 14001
certification of its products’ manufacturing sites.

Power distribution switchboards
These incoming switchboards, in the tertiary or industrial sector, are mainly
equipped with industrial switchgear of the Masterpact/Compact/Interpact type.
The control and isolation switch is an industrial device with the following ratings:
■ 400 A to 1000 A in the tertiary sector,
■ 400 A to 1600 A in the industrial sector.
Applicable standard: IEC 60947-3.
052838
ndustrial subdistribution switchboards or automation cubicles
As a rule, the incomer is an industrial device with a rating ≤ 400 A.
According to its rating, the most frequent cases are:
■ for incomers ≤ 160 A, feeders of the Multi 9 type and switchboards designed to
receive this switchgear type,
■ for incomers from 160 to 400 A, industrial type feeders such as the Compact NS:
❏ in industrial distribution switchboards,
❏ in automation cubicles,
■ for incomers from 40 to 400 A, control and monitoring feeders installed on
universal mounting plates.
Applicable standard: IEC 60947-3.
22
Subdistribution switchboards (modular products)
The incomer is normally a modular type device ≤ 160 A.
Feeders are mostly made with modular switchgear.
All the devices are mounted in equipment systems adapted to the modular
switchgear (e.g. Prisma, Pragma).
Applicable standard: IEC 60947-3.
E52516
Small final distribution enclosures
As a rule the incomer is a modular type device ≤ 63 A.
Feeders are low rating Multi 9 circuit-breakers. All the devices are mounted in a
small modular enclosure.
The choice of INS63 or l63 depends on the type of application:
■ INS63 for the commercial and tertiary sectors.
Applicable standard: IEC 60947-3.
■ l63/ll00 for housing and domestic applications. It is often used as a direct control
switch on final circuits (e.g. control of heating, convector, etc.).

Applicable standard: IEC 60947-3.
Automation enclosures
The current range for this application is normally limited to 40 A. The enclosure is
frequently built into the machine.
The switches dedicated to this application are usually designed specifically for it
(standard ratings: 16/25 A).
This type of device normally includes many accessory possibilities (auxiliary
switches, optional door mounting, etc.).

4.2.2 Consistency of the circuit-breaker/switch
ranges
4.2.2.1 Size and accessories
055994
At power distribution level - 100 A to 630 A - it is essential for switch ranges to be
completely consistent with circuit-breaker ranges. Schneider Electric thus offers
Interpact INS / INV ranges that are fully in line with the Compact NS circuit-breaker
ranges.
Consistency is ensured for:
■ accessories (auxiliaries, rotary handle, etc.) shared by the 2 ranges,
■ dimensional features (pole pitch, physical size, etc.), particularly important,
■ design and colour.
Figure 12: Common Interpact INS and Compact NS accessories
E54475
E62422
This rationalisation guarantees this range perfect incorporation in the Prisma
functional installation systems. Furthermore, this switchgear can:
■ be mounted on symmetrical rail or on a functional mounting plate,
■ use the cabling accessories of Prisma Distribloc, Polybloc, etc.

4.2.2.2 Control auxiliaries
E62423
■ Rotary handles to satisfy all installation systems.
In particular, the INS/INV switches can be equipped with direct and extended
rotary handles of the front or lateral type.
The extended rotary handle maintains isolation with positive contact indication.
■ Connection accessories.
To simplify connection of some large diameter cables, a single-piece spreader
(also usable for Compact NS circuit-breaker ranges) allows:
❏ increase in pole pitch
❏ use of the connection and isolation accessories of the larger-sized device
❏ factory-guaranteed isolation quality.

4.2.2.3 Manual source changeover switches
E55272
E54481
A comprehensive manual source changeover switch range is available with an
interlocking system:
■ key-operated,
■ with rotary handles,
■ single-piece (INS switch).
O
Figure 15: Single-piece Interpact INS source changeover switch
This last option ensures rationalisation of the function:
❏ by optimised size of switchgear
❏ by implementation of a single 3-position rotary handle.
This guarantees greater ease of mounting and safety of implementation.
Consistency with the circuit-breaker ranges is respected thanks to identical fixing
centres and thus the same cabling gauge.
A downstream coupling accessory completes the simplicity of the source
changeover switch function (the same for two switchgear).

manufacturing process
In short
The switch must be chosen
according to:
■ the characteristics of the network
on which it is installed,
■ the location and the application,
■ coordination with the upstream
protection devices (in particular
overload and short-circuit).
4.3 Choosing a Schneider Electric switch
4.3.1 Choice criteria
4.3.1.1 Network characteristics
Nominal voltage, nominal frequency and nominal current are determined in the
same way as for a circuit-breaker:
■ nominal voltage = nominal voltage of the network,
■ frequency = network frequency,
■ nominal current = rated current of a value immediately higher than the
downstream load current. Note that the rated current is defined for a given ambient
temperature and that a derating may have to be taken into account.
4.3.1.2 Location and application
This determines the type and characteristics or main functions that the switch
must possess. There are 3 function levels (see table opposite):
■ Basic functions
virtually common to all switch types:
❏ isolation, control, padlocking, safety.
■ Additional characteristic functions
❏ direct formulation of the needs of the user and of the switch environment, i.e.:
- industrial type performance,
- need for emergency stopping,
- lsc level,
- type of interlocking,
- type of control,
- utilisation category,
- mounting system.
■ Specific functions
❏ linked to operation and to installation requirements, i.e.:
- earth leakage protection,
- motor mechanisms,
- remote opening (“emergency stop” function),
- withdrawability.
The following table enables choice of switch according to requirements.
■ Choice table
Comparison of the application table (§ 4.3.2) and the switch technical data table
(§ 4.3.4) lets you specify which switch range should be used.
4.3.1.3 Coordination
All switches must be protected by an overcurrent protection device placed
upstream.
The "additional technical information" tables below give the SCPD (circuit-breaker
or fuse) guaranteeing proper coordination with switches in event of a
downstream short-circuit, according to the electrodynamic withstand or the shortcircuit making capacity of the device.

4.3.3 The switches available in the Schneider Electric
offer
Renewal and standardisation of the Interpact range is part of the Schneider
Electric global offer.
Schneider Electric offers its customers several ranges of switches.
Choice depends on:
■ the application,
■ the additional functions to be implemented (safety level, convenience, etc.).
The following table summarises the possibilities offered by all the Schneider
Electric ranges according to the applications described above.

Compact NS100NA
Compact NS100NA to NS250NA switchdisconnectors are obtained by mounting an
NA switch-disconnector module on the
basic NS100 to NS250 frames.
Compact NSA125NA and NSA160NA
switch-disconnectors are supplied fully
assembled.
Switch-disconnector protection
According to installation standards, an
upstream protection is required.
Nonetheless, due to reflex tripping,
Compact NS100NA to NS250NA switchdisconnectors self-protect for all fault
currents greater than 10 kA.

Co-ordination
Modular switches and residual
current circuit-breakers
Presentation
The choice of a switch should be made
according, among other things, to coordination with the device for protection
against short-circuits, installed upstream.
The switch, whether it be a residual
current circuit-breaker or not, has a
breaking capacity and withstand to limited
short-circuit currents and should be
protected against short-circuits which
develop downstream (electrodynamic
protection).
The following tables indicate the
maximum short-circuit efficient in kA
from which the switch is protected
thanks to co-ordination with the
corresponding circuit-breaker placed
up-stream.
Caution: the switch should also be
protected against overloads.
When the residual current circuit-breaker
and the downstream circuit-breakers are to
be found on the same switchboard, set up
according to the rules, the protection of the
residual current circuit-breaker from shortcircuit currents can be ensured by each of
the circuit-breakers placed downstream.
The corresponding values are the same as
in the case of co-ordination with a device
located upstream.
The table below allows co-ordination tables to be selected which should be taken into
account depending on the upstream and downstream devices.

b An enclosure’s outgoer, where the Isc on
the busbars is 20 kA, supplies loads with
current ratings of 30, 20 and 10 A
respectively in single phase, 230 V
b The installation’s neutral system is the TT
earthing system
b The outgoer located on the upstream
switchboard, which supplies this
enclosure, is protected by a 2-pole C120N
circuit-breaker.

ID and multi 9 circuit-breakers
Which residual current circuit-breaker
should you choose to equip the
enclosure’s incoming feeder?
b Choose an ID residual current circuitbreaker with a rating u 30+20+10 u 60A,
or an ID rating of 63 A
b Short-circuit withstand of the ID 63A
combined with C120N: the table (page 58)
includes 10 kA, which is not enough to
withstand 20 kA
b It is possible to co-ordinate each of the
enclosure’s outgoing lines since the
feeders are located in the the same
enclosure as the switch
b Choose C60N type circuit-breakers for
feeders with a short-circuit withstand
of 20 kA.
Short-circuit withstand of the ID 63A
combined with C60N is of 20 kA and is
suitable.

Co-ordination
Industrial switch-disconnectors
Example
A low voltage distribution switchboard 400 V / 230 V, with a short-circuit current of 35 kA at
the level of the busbar, possesses an outgoing feeder with a nominal current of 60 A. The
wiring system which supplies this outgoing feeder is protected with a NS100H (R.B.: 70 kA)
switch. This wiring feeds a sub-distribution switchboard, where the intention is to install, at
the incoming feeder, a circuit breaker to ensure that the control and isolation functions are
performed.
The short-circuit current at the level of the sub-distribution switchboard is 30 kA.
Which switch is the right one ?
If the auxiliary functions such as remote control, earth leakage protection are requested, then
the Compact NA switch would be the appropriate switch ; its coordination characteristics are
given in the tables which follow (page 62 and following). The NS100NA switch is also
appropriate, due to the fact that the association withstand with the NS100H is 70 kA.
Furthermore, the NS100NA switch is self-protected from 10 kA upwards.
If no auxiliary function is requested - or if it is matter of auxiliary functions in the form of
auxiliary contacts, rotary handles - then the Interpact INS100 would be suitable (see tables
page 62 and following).
E62588
The table reading page 63 shows that the INS100 characteristics, when coordinated with the
NS100H, become (following item) :
b 70 kA for the Isc withstand
b 154 kA peak for the making capacity.
Icc = 35 kA
NS100H
coordination
1 = 60 A
Icc = 35 kA
The rating of the INS100 is compatible with the line's nominal current: 60 A.
Reading of tables
(pages 62/63)
E62589
By coordination:
b Isc withstand is more than sufficient: 70 kA
b Making capacity on the peak Isc 154 kA is considerably higher than the requirement.
Note: for Isc = 30 kA, Imax peak ~ 75 kA.
