Circuit breaker is a kind of basic low-voltage electrical appliances, circuit breaker is used for overload short circuit and low voltage protection also has the ability to protect circuit and power supply. Its main technical indicators are rated voltage and rated current . Circuit breaker have different functions and varieties of technical specification according to different applications.
