DZ47-63 air switch DZ47 1P 2P 3P 4P 10A 16A 20A 32A 40A 63 small circuit breaker.

Brief introduction

DZ47 miniature circuit breaker is a lightning protection measure independently developed by Zhejiang tol Electric Co., Ltd., aiming at household circuit. The series of circuit breakers have excellent performance in order to avoid the above failures. The differential coordination characteristics of circuit breakers are the best products at home and abroad.

Product features

1. high quality connection te rminal

2. High capacity of rated short circuit

3., with finger contact protection combined terminal, the safety is higher.

Use of attention

1. grade of pollution: the grade of anti pollution is grade 2 or grade 3.

2. general vertical installation. The handle is upwards to connect the power source position, allowing any position to be 2 degrees.

3. check whether the technical parameters on the pad are in line with the requirements.

Product specification

Working principle of product

A small circuit breaker is the principle that the bimetal bending is directed regularly with the increase of temperature. When the circuit breaker is closed in normal working condition, the internal bimetallic sheet is heated by a certain current, and the thermal expansion coefficient of the two bimetalles is different. It is not enough to release the release mechanism. When the line appears general overload, when the overload current is reached, the bimetallic sheet has a larger bending angle and a lever in the release mechanism, which is enough to push off the release mechanism, and from the small circuit breaker, it plays the role of super load protection. The size of the bimetallic strip is different from that of the small circuit breaker.
