Lexic:
who better than
you to talk about it!
A COMPLETE RANGE FOR ALL APPLICATIONS
In choosing Lexic, I feel we have opted for a universal
solution which answers all the problems we may
encounter on site. This complete range guarantees consistency
and uniformity in our consumer units.
Lexic: a universal
range
Equally well suited to residential applications and large commercial installations,
Lexic offers a complete range of protection devices and control/signalling auxiliaries.
From 3000 A in accordance with domestic standard IEC 60898-1 to 50 kA for industrial
standard IEC 60947-2, it is now one of the most comprehensive offers on the market and
also ensures superb aesthetics and overall uniformity of appearance.
The wide
choice of
residual current
devices means
people can be
protected in any
scenario.
Being compliant with both
the IEC 60898-1 and IEC
60947-2 standards, Lexic
dx and dx-H MCBs are
suitable for a very wide
range of applications:
domestic, commercial and
industrial.

01
I know that Legrand attaches particular importance
to the performance of its Lexic circuit breakers.
Individually tested in the factory and conforming to international
standards such as NF, the user can be sure of high-quality
operation. We find it very reassuring!
02
Lexic: impeccable
quality
Legrand pays particular attention to how these device perform, so each of them is set and
checked individually on the production lines.
Legrand's factories are certified ISO 9001 for quality and ISO 14001 for environmental protection.
The tripping
characteristics are
calculated and adjusted
to ensure correct
discrimination between
the different protection
levels in order to
improve the user
experience.
The different Hpi, the
impeccable quality of
the electronic circuits
and components are
designed to improve
continuity of service by
avoiding false tripping
and provide better
protection for people.
Lexic products are
certified in accordance
with international
product standards. All
approvals such as nF,
universally recognised
for its very high level
requirements, are
renewed annually.
THE BEsT-PERFoRMIng CIRCuIT BREAkERs
Lexic circuit breakers are in limitation class 3: they limit
the short-circuit power in the cables and can prolong the
installation's life by avoiding damage to the cables caused by
the stress of power flowing through them. Products never work
at the “limit” of their capacity.
03
I really appreciate the chance to mix and match protection
and control devices on the same row. The Lexic range
offers us real freedom of installation while letting us stick to our
usual wiring practices!
04
Lexic: freedom of
installation
Mix and match any function with the Lexic concept: protection, control, and
signalling devices can thus be grouped by physical zone in the installation in
the same order as the circuit diagram. The control and signalling devices and
auxiliaries have a slot to allow the supply busbar to pass through.
Each circuit breaker
can take up to
3 auxiliaries and
1 add-on module.
The auxiliaries are
common to the whole
Lexic range.
Monobloc
RCBos up
to 63 A save
precious
space in
switchboards.
Lexic devices can
be supplied with
power via the
bottom or the top
to suit all types of
wiring practice.
05
The Lexic range is reassuringly well designed. All the
devices have 35 mm² terminals so I can make connections
which are perfectly safe. I have complete peace of mind when wiring
up my switchboards.
06
Lexic: safety and
ease of connection
The Lexic range ensures safety of installation and simplifies wiring operations.
With wide terminals providing reliable, lasting connections, a wire guide and
enhanced cable tensile resistance, Lexic ensures ease of installation and peace
of mind.
The Lexic range guarantees
IP2x protection. It prevents
any risk of contact with
live parts, even when the
faceplate is open.
Lexic devices have a
wire guide flap on their
terminals, which avoids
connection errors.
Prong or fork-type
supply busbars eliminate
any risk of short-circuits
and provide a totally
reliable connection via the
top or bottom of the device.
Easy to use, they can be
adapted to suit any type of
connection practice.
ExCLusIVE To LEgRAnd
ALL LExIC swITCHEs And CIRCuIT BREAkERs HAVE LARgECAPACITy 35 MM² TERMInALs FoR EAsE oF ConnECTIon.
- The shape of the screws and terminals guarantees excellent
mechanical withstand of the wires and limits the contact
impedance, temperature rise and heat loss.
07
Marking of product characteristics, protected
label holder… really useful features which save me
precious time when undertaking maintenance!
08
Lexic: simplicity and
safety of maintenance
The many advantages of the Lexic range can optimise intervention times during
maintenance operations without compromising on safety: product marking, circuit
identification and coloured handles mean functions can be quickly identified…
Genuinely useful features which simplify operation and maintenance.
The label holder on the
product front face protects
the labels effectively and
durably so that the circuits
are easily identifiable.
To make it safe to work
on the consumer unit
and prevent accidental
restarts, the handles can
be padlocked.
double clips on the
back of the products
can be used to remove
individual devices without
unscrewing the whole row.

The clear and comprehensive

marking on the handle

n A type M - Specific applications: dedicated lines
In addition to the characteristics of AC type RCDs, A type RCDs also
detect DC residual currents
They are used whenever fault currents are not sinusoidal
They are particularly suitable for the following specific applications
(hobs, washing machines…) or materials may produce DC fault
currents, speed drives with frequency inverters, etc.
n Hpi type M H - Special applications
Type Hpi RCDs are devices which offer additional immunity to
unwanted tripping which significantly exceeds the level required
by the standard
They are also able to detect AC and DC residual currents (A type)
Operation between - 25 °C and + 40 °C
They are used in special applications where:
• Loss of information is potentially damaging, e.g. power supply lines
for computer equipment (banks, equipment on military bases, flight
reservation centres, etc.)
• Loss of operation is potentially damaging (automated machinery,
medical equipment, freezer cable, etc.)
They are also used:
• On sites where there is an increased risk of lightning strikes
(see p. 164)
• On sites where cables are subject to high levels of interference
(use of fluorescents, etc.)
• On sites where very long cables are used

performance of MCBs and auxiliaries (continued)
n Protection of DC circuits
Lexic DX and DX-H MCBs (1P/2P/3P/4P - In ≤ 63 A) designed for use in
230/400 V± supplies, can also be used in DC circuits
In this case, the following deratings and precautions must be taken into
account
1 - Protection against short-circuits
Max. magnetic tripping threshold: multiplied by 1.4
Example: For a C curve MCB for which the AC tripping threshold is
between 5 and 10 In, the DC tripping threshold will be between
7 and 14 In
2 - Protection against overloads
The time/current thermal tripping curve is the same as for AC
3 - Operating voltage
Max. operating voltage: 80 V per pole (60 V for single-pole + N MCBs)
For voltages higher than this value, several poles must be wired in series
Example: for a 110 V voltage,
use a 2-pole MCB and connect
the 2 poles in series
Example: circuit earthed via the negative polarity / U = 110 V= / Isc =
10 kA / In = 32 A
Protect the positive polarity using an MCB capable of breaking 10 kA
at 110 V (DX-H 2P 32 A with 2 poles on the positive polarity)
For isolation, use a DX-H 3P 32 A with 2 poles on the positive polarity
and one pole on the negative polarity

5 - Distribution of breaking poles
To choose the MCB and determine the pole distribution necessary
for breaking on each of the polarities, it is necessary to know how the
installation is earthed
• Supply with one polarity earthed:
Place all the poles necessary for breaking on the other polarity If
isolation is required, an additional pole must be added on the earthed
polarity

n Specific case of continuity of service
n 2P and 4P RCDs: withstand to short-circuits
In certain locations, where there are no personnel, in which particular
care is required to ensure continuity of service, false tripping of MCBs
is not permissible (isolated telephone/TV/radio relay stations, pumping
stations, etc.)
Caution: it is advisable to provide overload protection for the RCD
Downstream

The combination of an Hpi type RCBO with motor-driven control
and a recloser provides optimum continuity of service (p. 155)
