    Tips: Overload protection of miniature circuit breaker

    The overload protection function of the MCB breaker is based on the principle that the bimetal is oriented and bent regularly as the temperature rises. After the miniature circuit breaker is closed, in the normal working state, the internal bimetallic sheet generates heat due to a certain current passing through it. The two pieces of metal have different coefficients of thermal expansion and cause bending. The bending angle of the normal current (1.13In) is not large, so the thrust is not enough to trip the tripping mechanism. When the line is generally overloaded and the overload current (1.45In) is reached, the large bending angle of the bimetal touches the lever in the tripping mechanism, and the thrust is sufficient to push the tripping mechanism so that the micro circuit breaker trips and plays a role of overload protection. The magnitude of the current flowing through the mini MCB is different, and the degree of bending of the bimetallic sheet is also different. When the circuit is generally overloaded, the tripping time of the circuit breaker is generally longer because the overload current is not too large. The standard trip current is 1.45 times the rated current. The trip time should be within 1 hour.

    Types of Circuit Breakers

    In this video, we'll take a closer look at the meaning behind these abbreviations and explain the types of circuit breakers they represent. By understanding the different types of circuit breakers on the market, you can make an informed decision and choose the right type for your specific requirements, thereby enhancing the protection of your electrical infrastructure.

    Isolator vs Circuit Breaker

    Although isolators and circuit breakers have similar functions in a circuit, they are two separate entities. This video explains you the difference between the two devices in terms of working, features, operation, affordability, etc. You can choose between them based on your specific requirements.
