ReleasesCircuit-breakers M4 are equipped with bimetallic-based, inverse-time delayed overload releases and with instantaneous overcurrent releases(electromagnetic short-circuit releases). The overload releases can be set in accordance with the load current. The overcurrent releases are permanentlyset to a value 13 times the rated current and thus enable trouble-free start-up of motors. The scale cover can be sealed to prevent unauthorizedadjustments to the set current. Operating mechanismsCircuit-breakers M4-32T are actuated via a rocker operating mechanism and circuit-breakers M4-32R, M4-63R...
