2P 3P 63-1600A ISOMAX Type Molded Case Circuit Breaker mccb China manufacturer high quality

Short Description:

1. Application of ISOMAX S moulded case circuit breaker

The ISOMAX series moulded case circuit breaker applies to break 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 a 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 infrequently. The other characters of the products are small size, large contact spacings, high capability of break-make, and short arcing distance. The performance is as well as the original S series circuit breaker. The product complies with the standards of IEC90947-2.
