Thermal-Magnetic Circuit Breaker 320-...-M-... Description Two pole rocker switch/thermal-magnetic circuit breaker with trip-free mechanism (S-type TM CBE to EN 6034). The addition of a magnetic tripping module to the type 320 range described in catalogue section Thermal Overcurrent Circuit Breakers extends the choices available (thermal-magnetic protection in pole, thermal or no protection in pole 2). All are offered with rocker switch or push button control - two buttons for ON/OFF or one button press-to-reset only, in designs to suit one of three different panel cut-out sizes. Illumination is optional. Approved to CBE standard EN 6034 (IEC 6034). Meets the requirements regarding fire resistance of EN 605-: 2007-02 Safety of household and similar electrical appliances. Typical applications 320-...-M... Motors, machine tools, office equipment, appliances.
