STRUCTURAL  FEATUES

1.HSX-250L Miniature Circuit Breaker or called MCCB is mainly used in the AC 50/60Hz rated operating voltage of 440V and below.

2.rated current of 250A 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.

3.Structural features of HSX-250L MCCB 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.

4.The parts of the operating mechanism of MVS-250N 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.

5.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. Circuit breaker is equipped with overload, short circuit and under voltage protection devices, so as to protect the circuit and E type compact power equipments from damage.
