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 three 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. 6-way 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.
●
Under voltage 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).

Thermal Overcurrent Circuit Breaker 3120-F7..
Description
E-T-A’s proven type 3120 in a new attractive styling (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 illumination as an option.
Under overload conditions the rocker returns to the OFF position.
Any one of the following additional function modules can be supplied factory
fitted to the rear of the switch/circuit breaker.
●
Under voltage 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).
Available accessories: water splash protection and actuator guard to prevent
inadvertent operation.
