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. the insulation resistance between the pole and pole (except the monopole), the end and the outlet end of the circuit breaker should be not less than 2M Omega, and the insulation resistance between the pole and the shell, the pole and the installation rail should not be less than 5M Omega. If the product is not required, the product shall not be used and should be exchanged in time with the supplier.
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 circuit breaker needs to check contacts after the circuit is short circuited. If the main contact burns seriously or has pits, it needs to be repaired.
