Special applications
Protection of industrial control panels
Compact NSX circuit breakers are also
used in industrial control panels.
They serve as an incoming devices or can
be combined with contactors to protect
motor feeders:
b
compliance with worldwide standards
including IEC 60947-2 and UL 508 / CSA
22-2 no. 14
b
overload and short-circuit protection
b
isolation with positive contact indication,
making it possible to service machines
safely by isolating them from all power
sources
b
installation in universal and functional
type enclosures
b
NA switch-disconnector version.
Industrial control panels
Compact NSX circuit breakers equipped for public distribution or motor protection
functions as described in the previous pages can be used in industrial control panels.
The accessories for the Compact NSX range are suitable for the special needs of
these switchboards.

All auxiliaries can be added to the circuit breaker by the user:
padlocking devices (in the OFF position)
b
rotary handle
b
status-indication auxiliary contacts (ON, OFF and tripped)
b
shunt (MX) or undervoltage (MN) releases
b
early-make or early-break contacts.
b
5RWDU\ KDQGOH
Direct or extended versions for mounting up to 600 mm behind the front:
black front with black handle
b
yellow front with red handle (for machine tools or emergency off as per IEC 204 /
b
VDE 0013).
All rotary handles can be padlocked in the OFF position. Optional door interlock,
recommended for MCC panels (motor control centres).
When the device is equipped with an extended rotary handle, a control accessory
mounted on the shaft makes it possible to operate the device with the door open.
The device can be padlocked in the OFF position in compliance with UL508.

These contacts can be used respectively to supply an MN undervoltage release
before the circuit breaker closes or to open the contactor control circuit before the
circuit breaker opens.
Special functions
Indication of thermal overloads with the SDx module.
b
Early opening of the contactor for overload faults with the SDTAM module.
b
Links with PLCs via the communication system.
b
Measurement of all electrical parameters with Micrologic A and E.
b
Programmable alarms with Micrologic 5 and 6.
b
Installation in enclosures
Compact circuit breakers can be installed in a metal enclosure together with other
devices (contactors, motor-protection circuit breakers, LEDs, etc.)
(see page A-90)
.
Compliance with North American
industrial control equipment standards
Compact NSX devices have received UL508 / CSA 22-2 no. 14 approval for
industrial control equipment of the "Manual Motor Controller", "Across the Line
Starter", "General Use" and "Disconnecting Means" types.
Type NA devices are switch-disconnectors that must always be protected upstream.
