Molded Case Circuit Breaker

P/N & Price

Molded Case Circuit Breakers(MCCBs) are used basically protects the entire electrical system from overloading and having such conditions of short circuit issues. Them are widely used in the new energy, power, industrial control, electric power, telecom, project construction, etc.

Molded Case Circuit Breakers-MCCBs

The circuit breakers are used with AC voltage for distributing power while protect the overload, short circuit and under-voltage (with a under-voltage release) of lines and power units as well as the infrequent starting, braking, overload and short circuit of motors. 

Main features

  • Rated current from 10A to 1250A.

  • Working voltage from AC 230V to AC 1000V.

  • 2 poles, 3 poles, 4 poles.

  • Extreme breaking capabilities and reliable performance under pressure.
