CNSV 160F-3P molded case circuit breaker

Detailed instructionsUsage and scope of application

CNSE series of MCCB reflects the latest current limiting principle and manufacturing technolgy, characterized by compact structure, full modularization, high breaking and zero arcover. Its rated insulation voltage is 800V, rated operating voltage is AC 50/60Hz, 690V and below, rated current up to 800A. Circuit breaker is equipped with overload, short circuit and under voltage protection devices, so as to protect the circuit and power equipment from damage.
