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:
