Mini 3 / 4 Pole Home Miniature Circuit Breaker Air Switch Overload Protector

DZ47 1P 2P 3P 4P 10A 16A 20A 32A 40A 63 home mini circuit breaker air switch overload protector.


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. double connection function. It can connect standard remittance and soft conductor conveniently.


2. band energy storage mechanism operation, contact close fast


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


Use of attention


1. the load connection of the leakage circuit breaker must pass through the load end of the circuit breaker, and no any line or zero line of the load does not pass through the leakage circuit breaker. Otherwise, the "leakage" will result in the circuit breaker closing, causing "misoperation". Besides, in order to protect the line and equipment more effectively, the leakage circuit breaker and fuse can be used together.


2. 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.


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