A low-voltage electrical switchgear is a component or device that can be switched on or off automatically or automatically to switch, control, protect, detect, transform, and regulate circuits or non-electrical objects in accordance with external signals and requirements. Control of electrical appliances according to the level of its work to AC 1000V, DC 1500V for the sector, can be divided into high-voltage control appliances and low-voltage control of two major categories of electrical appliances. In general, low-voltage electrical appliances can be divided into two categories of electrical distribution and electrical control, electrical equipment is the basic components of complete sets of components. In the industrial, agricultural, transportation, national defense and people's electricity sector, most of the use of low-voltage power supply, so the quality of electrical components will directly affect the reliability of low-voltage power supply system.
Low-voltage electrical appliances generally have two basic parts: one is the sensing part, it senses the outside signal, makes a regular reaction, in the self-control electrical appliances, the sensing part is mostly composed of electromagnetic institutions, in the controlled electrical sense The measuring part is usually the operating handle, etc .; the other is the implementation of the part, such as the contact is based on instructions to open or cut off the circuit.
