Type: 3120-F
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:
Undervoltage release coil (for double pole versions only).
Magnetic trip coil for short circuit protection.
Magnetic trip coil for remote relay trip.
Auxiliary contacts for status signalling.
Mechanical slide interlock.
Approved to CBE standard EN 60934 (IEC 60934).
