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. 1 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. 3120-F... Approved to CBE standard EN 60934 (IEC 60934).
