400A 4P Moulded Case Circuit Breaker Thermal Switch Mccb
Usage and scope of application
The design of CNSV series of MCCB 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 690V, rated operating voltage is AC50/60Hz, 440V and below, rated current up to 630A. It's used for generating infrequent conversion and infrequent startup of the motor. 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.
