Thermal Overcurrent Circuit Breaker 3120-F...
Description
An extremely versatile range of rocker switch/thermal circuit breakers
(S-type TO CBE to EN 60934 with trip free mechanism) offering the
choice of single pole, double pole with single pole protection, and
double pole with protection on both poles. Designed for snap-in panel
mounting with versions available for different panel cut-out sizes.
Illumination is optional and there is a range of colours and markings for
the rocker. Under overload conditions the rocker returns to the OFF
position. 6way frame for 3120-F5 available upon request.
Any one of the following additional function modules can be supplied
factory fitted to the rear of the switch/circuit breaker.
q
Under voltage release coil (for double pole versions only).
q
Magnetic trip coil for short circuit protection.
q
Magnetic trip coil for remote relay trip.
q
Auxiliary contacts for status signalling.
q
Mechanical slide interlock.
Approved to CBE standard EN 60934 (IEC 60934).

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:
q
Under voltage release coil (for double pole versions only).
q
Magnetic trip coil for short circuit protection.
q
Magnetic trip coil for remote relay trip.
q
Auxiliary contacts for status signalling.
q
Mechanical slide interlock.
