Circuit Breaker Information
Circuit Breaker Dimension (Unit: mm)
Tips: What is a circuit breakerCircuit breaker is a switching device that protect an electrical circuit from damage caused by overcurrent, typically resulting from an overload or short circuit. Circuit breaker can be used for distributing electric energy, starting asynchronous motors infrequently and protecting power circuit and motors. They can automatically cut off the circuit where major failures occur such as overload, short circuit and under-voltage etc, which is equivalent to the combination of fuse switch and overheat relay. According to the range of application, they are divided in to high-voltage circuit and low-voltage circuit breakers, and high-voltage ones above 3kV are known as high-voltage electrical apparatus.
