INTRODUCTION OF LOW VOLTAGE CIRCUIT BREAKER

Low-voltage circuit breakers are also called automatic air switches or automatic air circuit breakers, or circuit breakers for short. It is an electrical appliance that not only has the function of a manual switch, but also can automatically protect against loss of voltage, under voltage, overload, and short circuit. It can be used to distribute electric energy, start asynchronous motors infrequently, protect power lines and motors, etc., and automatically cut off the circuit when they have serious overload, short circuit, and under voltage faults. Its function is equivalent to a fuse switch and Combinations of overheating and under heating relays. Moreover, it is generally not necessary to change parts after breaking the fault current, which has been widely used.
