Use and scope of application

NMDZ47-100 (NC) series high-breaking miniature circuit breakers are suitable for AC 50Hz, rated voltage unipolar, two-pole 230v, three-pole, four-pole 400V, rated current from 63A to 125A, can protect the line motor overload or short circuit It can also be used between infrequent switching of lines and infrequent starting of electric motors.

This product complies with EC60898, GB 10963.1 standard.

Structural features:

The circuit breaker operating mechanism is a free-locking mechanism with energy storage type, and the contacts are quickly closed, which overcomes the adverse effects caused by the speed of the manual operation handle and greatly improves the service life of the product;

In normal operation, the contacts can only stay in the closed or open position;

The shell and parts are made of high flame retardant, high temperature resistant and impact resistant plastic;

The signal control trip unit is composed of a thyristor, an electromagnetic trip, and the like.
