Circuit Breakers: Low-voltage circuit breakers, also known as automatic switch, it is the role of both a manual switch, but also automatic loss of pressure, voltage, overload, short-circuit protection and electrical appliances. It can be used to distribute electricity, no frequent start asynchronous motors, the implementation of the protection of power lines and motors, if they are serious overload or short circuit and undervoltage fault can automatically cut off the circuit, which functions as a switch and fuse owed by combining thermal relay or the like. And after breaking the fault current is generally not necessary to change parts, gained a wide range of applications.
(1) circuit breaker accessories
(2) miniature circuit breakers: miniature circuit breakers, Acronym MCB, the terminal building electrical distribution equipment used in the most widely used to protect electrical terminal
(3) MCCB: MCCB can automatically cut off after the current exceeds the current trip setting. Molded plastic insulator refers to as the shell means for isolation between the conductor and a ground metal parts. Molded case circuit breakers usually contain thermal magnetic trip units, although larger sizes MCCB equipped with solid state trip sensors.

Intelligent Power Distribution:
(1) low voltage reactive compensation package devices
(2) the combination switch
(3) operating handle
(4) reactive power compensation controller
Low-voltage distribution switch:
(1) load switch: load switch, as the name suggests is that we can cut off the load current switch, to distinguish it from high voltage circuit breakers, load interrupter switch is not ability, not breaking fault current, only breaking load current system under normal operating conditions , load switch, hence its name
(2) isolation switch: high voltage switch electrical isolation switch is one of the most used appliances, its own principle and structure is relatively simple, but due to the use of a large amount of work that require high reliability of substations, power plant design affect the safe operation of the establishment and are larger. The main features of the knife is not breaking the ability, not only in the current case load points, co-circuit measures.
