1. Application Of Moulded Case Circuit Breaker

ZQM1 series moulded case circuit breaker applies to breaking and making operation in AC 50/60Hz, rated operation voltage 690V or less and rated current up to 2000A circuit. It can distribute electric energy in circuit, work as the overload of wiring and power supply equipment, or as the protector of short circuit and under voltage. Additionally, this breaker can switch line and start motor unfrequnently. The other characters of the products are: small size, large contact spacings, high capability of break-make, and short arcing distance, this performance is better than that of CM1 series. This performance is as well as original S series circuit breaker. The product complies with the standards of IEC90947-2.
