NM5PDS series electronic molded case circuit breaker

Function and use

Chint NM5PDS series plastic case circuit breakers are suitable for AC 50/60Hz, rated voltage AC690V and below, and rated current 63A to 630A circuits. As a means of making, breaking and carrying rated current, it can reliably protect lines and electrical equipment when they are overloaded, short-circuited or under-voltage.
