Manhua MCB MK7-63 C63 2P 63A 400VAC breaking capacity Overload Protection Short circuit protection Miniature Circuit Breaker

Description:

MK7-63 Miniature Circuit Breaker or called MCB is mainly used in the AC 50 / 60Hz, rated operating voltage of 400V and below, rated current of 63A circuit, the circuit breaker is mainly used in electrical wiring of modern buildings and overload, short circuit protection of equipment, also applies to infrequent operation and isolation of the line. Structural features of MK7-63 MCB is composed of the plastic casing, operating mechanism, contact arc system, trip mechanism and other components. The casing uses a special plastic with high flame retardant and high strength, it has high impact resistance and light-weight. The parts of the operating mechanism of MK7 Circuit Breaker are made of high-strength plastic, which ensures the sensitivity and reliability while obtaining the lowest moment of inertia so that the time from the short circuit fault to the trip mechanism operation is short. The tripping mechanism is composed of a bimetal over-load reverse-time trip mechanism and a short-circuit instantaneous electromagnetic mechanism. Contact arc system uses a special guide arc angle and aisle off room, and has significant current limiting characteristics.
