Air Switch Bipolar Miniature Circuit Breaker Home Short Circuit Overload Protector

P63A air switch, bipolar circuit breaker C45 DZ47, home short circuit overload protector.

Product introduction

DZ47 circuit breaker has super first-class current limiting performance, it can accurately protect relay protection and automatic device from overload, short circuit and other fault hazards. The circuit breaker has the advantages of current limiting and arc extinguishing ability. Through a large number of comprehensive scientific experiments, it can realize the full selective protection between the main (sub) screen, protection screen and relay screen in the DC system below 3000Ah.

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

2. the setting temperature of the series circuit breaker is 30 +5 C. If a number of circuit breakers are loaded into the sealed box at the same time, the temperature of the box is raised correspondingly, and the current is 0.8In.

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