Professional Manufacturer Supply STM7-63 Miniature Circuit Breaker 10KA 1P 2P 3P 16A 230/400V High Breaking Capacity MCB
General
STM7-63 Series miniature circuit breaker is nice in appearance, reasonable in structure, sound in feature, high in breaking capacity and its shell and parts are made of material with impact resistance. It is mainly used in the line of 50/60Hz, rated working voltage to 230V/400V, and rated current to 63A as protection against overload and short-circuit. It is mainly applied at office building, residence, for lighting, power distribution and overload and short circuit protection of equipment. Normally, it also can be used as the not frequent transfer of power system. It complies with standard IEC60898.1 and GB10963.1
