Thermal Overcurrent Circuit Breaker 3120-F...
Description
Switch/thermal trip free circuit breaker (S-type TO CBE to EN 60934) with
standard isolator style two button operation. Single button press-to-reset
version also available. Both types can be supplied in single pole configuration
only, in double pole with single pole protection, and in double pole with
protection on both poles. Designed for snap-in panel mounting. There is
a choice of push button colour combinations and illumination is optional.
Any one of the following additional function modules can be supplied factory
fitted to the rear of the switch/circuit breaker:
l
Under voltage release coil (for double pole versions only).
l
Magnetic trip coil for short circuit protection.
l
Magnetic trip coil for remote relay trip.
l
Auxiliary contacts for status signalling.
Approved to CBE standard EN 60934 (IEC 60934).
Meets the requirements regarding fire resistance of EN 60335-1 : 2007-02
Safety of household and similar electrical appliances.
