House Terminal Modular Circuit Breaker High Limiting Coefficiency Fire Line Only

DZ47 air switch household miniature circuit breaker 1P2P3P4P1-63A protection switch

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 one of the most widely used terminal protector used in the electrical terminal distribution device, which can quickly break down the fault current of the DC distribution system, so that the gradation coordination can be greatly improved.

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.

Use of attention

1. check the circuit breaker together and check several times to check whether the operating mechanism of the circuit breaker is stuck or not, and whether the action is reliable.

2. the sectional area of the connection conductor should be adapted to the rated current of the circuit breaker.

3. the circuit breaker is broken due to the failure of the protection circuit (leakage, overload or short circuit), then the handle is in the release position (middle position). After finding out the cause of the failure, the operating handle should be pulled down (or placed in the "sub" position), and the operation mechanism can be closed after the operation (please pay attention to the different meanings of the three positions of the operating handle of the circuit breaker).
