Fuse switch disconnector
type NALF
1. GENERAL
Fig. 1
Fig. 2
The switch disconnector system NAL/NALF is based on a modular
principle. The basic unit consists of a frame with insulators and current
carrying parts. Two different types of operating mechanisms: snap action
mechanism type K or stored spring energy mechanism type A, can be
mounted on the frame. Fuse bases type F with tripping mechanism can
also be fitted. A triple pole earthing switch type EB with a snap action
mechanism and making capacity is also available. These different
modules can be combined in various ways in order to meet your specific
requirements.
Accessories such as shunt trip, under-voltage release, auxiliary switches,
motor operation and various systems for manual operation can easily
be added.
ABB’s switch disconnector type NAL and fuse switch disconnector type
NALF have primarily been developed for use within the following areas:
- as line and transformer switches within distribution networks
- as motor switches
- as capacitor switches
By combining NAL, which disconnects load currents and small fault currents
circuit, with a current limiting fuse (F), which breaks large short circuit
currents, the result is an ideal combination. This combination (NALF)
provides protection towards all types of faults in the network.
ABB has been producing switch disconnectors for more than 50 years.
The NAL was introduced in 1978 and has been undergoing continuos
development to satisfy the users’ demands.
More than 500 000 switches have been produced and are sold throughout the world.
The switch disconnectors meet IEC Publication 60129, 60265, 60694,
62271, GOST 1516.3-96, GOST 17717-79, ANSI Standard No. C37.20.4
and CSA Standard No. C22.2, No. 193 concerning switches for general use
and for safe co-operation between switch disconnector and fuse.

2. SHORT-CIRCUIT MAKING CAPACITY
With carefully designed contact geometry and high contact velocities
the NAL switches are able to close safely on short circuits of up to
1550 MVA at 36 kV.
3. ENVIRONMENTAL WITHSTAND ABILITY
The switch disconnectors comply with IEC requirements for equipment
for indoor use. The mechanisms are corrosion protected by zink plating
and a supplementary chromate treatment, and the frames are painted
with corroision resistant powder coating. In order to ensure a safe
operation even after years in service under all climatic conditions, the
mechanisms are generally fitted with plastic bearings.
NAL switch disconnector is manufactured according to our strict quality
and environment procedures.
Our ISO 9001 and ISO 14001 certifications assures the quality and
environmental excellence.
NAL switch disconnector is 98,64% recyclable.
4. FUNCTIONAL DESCRIPTION
To ensure correct operation for all relevant currents, the switch
disconnector system NAL/NALF is equipped with a dual arc extinguishing
system. When interrupting the current, the arc will be exposed to:
a) A current independent air blast which automatically starts at the
correct time during the interrupting process. This is achieved by
designing the insulators on the opening side as cylinders with
pistons. The pistons are connected to the mechanism in the
same way as the moving contacts. The air blast therefore starts
simultaneously with the contact movement (autopneumatic air blast).
b) A current dependent gas blast which occurs when the walls of
the arcing nozzles are exposed to the hot arc.
During this process, large volumes of gas are released and the
arc is effectively cooled. The concentration of the developed
gas increases with increasing current. The so called Hart gas effect
is therefore most important at high currents.
ABB

Triple-pole switch disconnector
type NAL
Fuse switch disconnector
type NALF
A well balanced utilization of these two effects has resulted in an arc
extinguishing system with a high reliability for all relevant currents.
Because of the autopneumatic air blast it will only be necessary to utilize
the Hart gas effect for the high currents. This gives an arcing system which
can withstand a large number of operations without excessive wear.
Consequently the NAL switches comply with highest electrical perfomance
classes of IEC 60265-1 (for selected nominal voltages only).
5. STANDARD FEATURES
NAL
The standard feature consists of chassis, insulators and current
carrying parts with the following pole distance:
12 kV
– pole distance 150 mm, 170 mm and 210 mm
17,5 kV
– pole distance 170 mm and 210 mm
24 kV
– pole distance 170 mm*, 235 mm and 275 mm
36/40,5 kV – pole distance 360 mm
* - with insulating barriers
Fig. 3
Rated currents are 400, 630 and 1250 A up to 24 kV
and 630/800 A for 36/40,5 kV
NALF
Fig. 4
Is delivered with the same pole distances as the standard feature.
Fuse base type F is delivered for installation on both the opening
side and the pivot side, with or without automatic tripping.
Fuse base with 6 insulators can also be delivered separately with
signal at fuse blown, or for installation on the pivot side of the switch.
6. MECHANISMS
A-MECHANISM – with two springs.
The opening spring is always charged before the switch can be closed by
means of the closing spring. This means that a closed switch always has the
opening spring charged, and the switch can be tripped immediately by hand,
electrically or by a fuse-link striker system.
K-MECHANISM – with one spring
Fig. 5
Closing or opening the switch is performed by charging the spring past
the dead centre.
KS-MECHANISM
is a standard K-mechanism equipped with a latching mechanism type
S, which results in the latch being stopped past the dead centre.
Thereby, the mechanism is ready for opening/closing by an operating
coil or pneumatically by a pump.
NB!:
Fig. 6
- The switching operation can not be completed by the
operating handle.
- The spring must be charged before each operation.
The KS combination is suitable for remote operation in case where the
spring mechanism can be charged manually.
KS-mechanism can not be mechanically interlocked.

EARTHING SWITCH TYPE E – with snap action spring mechanism
Fig. 8
The earthing switch can be mounted on the pivot side of the switch
and on the fuse base when the latter is on the pivot side of the
switch.
EARTHING SWITCH TYPE EB – can be delivered for separate
installation.

FUSE BASES TYPE F
with or without automatic tripping of the switch by the fuse-link striker
system. The fuse base can be mounted on both sides (i.e. opening
side or pivot side of the switch).
8. MOTOR OPERATION
The motor operation is very flexible when it comes to installation. It
can be installed at the switch axle’s right or left side, directly on the
switch or on the axle’s extension.
Can be delivered for all normed voltages.
Fig. 10
If motor operation is desired mounted on the front panel,
UEMC40A2 can be used.

MECHANICAL INTERLOCKING BETWEEN SWITCH AND
EARTHING SWITCH
At earth on fuse base, the interlocking design depends upon the
length of the fuse. Therefore, the fuse size must be stated.
KS-mechansism can not be interlocked to earthing switch (fig. 20).
