Two / Three Pole Miniature Circuit Breaker , Small Air Circuit Breaker

circuit leakage breaker, leakage protector, small air switch circuit breaker DZ47.

Product Details

   DZ47 miniature circuit breaker is a lightning protection measure independently developed by Zhejiang tol Electric Co., Ltd., aiming at household circuit. It is mainly used for the overload and short circuit protection of electrical lines and equipment of modern buildings. It is also suitable for the infrequent operation and isolation of the lines. It can quickly break down the fault current of the DC distribution system and improve the gradation coordination.

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.

Product features

1. advanced production process and beautiful appearance

2. safety insulation of fire retardant and high flame retardant material

3. long service life

Use of attention

  1. if the circuit breaker can't be broken, it means that the circuit breaker or line is defective. It needs to be overhauled.

  2. when the circuit is connected, check whether the wiring is correct. It can be checked by the test button. For example, the breaker can be correctly broken, indicating that the installation of the leakage protector is correct, otherwise, the line should be checked and the trouble should be eliminated. After the leakage protector is put into operation, every time after a period of time, the user should check whether the circuit breaker is running normally through the test button.

  3. altitude: the altitude of the installation site is no more than 2000m.
