A circuit breaker is a switching device that can automatically open or close a circuit. It is mainly used to control and protect circuits and electrical equipment to prevent overload, short circuit, undervoltage and other faults. There are many types of circuit breakers. According to different structures, uses, rated currents, breaking capacities, etc., the circuit breakers produced by our company can be divided into the following types:
Air circuit breaker (ACB): It is a large-capacity circuit breaker. All its parts are installed in a metal frame. It can be equipped with a variety of accessories. It has high breaking capacity and flexible protection functions. It is suitable for power supply main switch, busbar contact switch, large motor control switch and other occasions.
Molded case circuit breaker (MCCB): It is a small and medium-capacity circuit breaker. Its main components are installed in a plastic shell. It has a compact structure and is generally not repairable. It is suitable for branch circuit protection switches. It can have overload, short circuit, undervoltage, leakage and other protection functions.
Miniature circuit breaker (MCB): It is a small-capacity circuit breaker, mainly used for terminal distribution devices in residential and small buildings. It can have overload, short circuit, overvoltage, loss of pressure, leakage and other protection functions. It is easy to operate, safe and reliable.
