The low voltage switchgear is an important component of electrical systems for managing electric currents lower than 1,000 volts. Because it has a main function of circuit protection, control and switch, it is absolutely necessary for safe operation to electrical equipment low voltage switchgear. The low voltage switchgear includes such technological features as compact designs, modular manufacturing and advanced components like circuit breakers and contactors. This design makes maintenance work easier and economical without sacrificing reliability Low voltage switchgears has two general applications: Industries and commercial buildings, residential areas. In these places it helps to manage electricity distribution in order for the power supply distribution can be well regulated on the one hand to keep a local area from failing and on the other hand to cut down wires.
