product description
Molded Case Circuit Breakers CVS-250
Application
The design of CVS series of MCCB(shorted as circuit breaker) reflects the latest current limiting principle and manufacturing technology, characterized by compact structure, full modularization, high breaking, and zero arcover. Its rated insulation voltage is 750V, rated operating voltage is AC50/60Hz, 690V and below, rated working current up to 630A. It’s used for generating infrequent conversion and infrequent startup of the motor. Circuit breaking 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.
