Use and scope of application

NMDZ47LE-100 series high-breaking miniature circuit breaker is suitable for AC 50H, rated voltage unipolar two ends, two poles 230V three poles, four poles 400V, rated current from 63A to 125A line, can protect the safety of personal and electrical equipment, Protecting the line motor from overload or short circuit can also be used between infrequent switching of the line and infrequent starting of the motor.

This product complies with IEC60898 and GB10963.1 standards.

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.
