Control electrical appliances can be divided into high voltage control electrical appliances and low voltage control electrical appliances according to the level of their working voltage, with AC 1200V and DC 1500V as the boundaries.
A low-voltage electrical appliance is a component or device that can manually or automatically turn on and off a circuit according to external signals and requirements to achieve switching, control, protection, detection, transformation, and adjustment of circuits or non-electrical objects.
In general, low-voltage electrical appliances can be divided into two categories: distribution appliances and control appliances, which are the basic components of complete electrical equipment. In the industrial, agricultural, transportation, national defense, and people's electricity sectors, most of them use low-voltage power supply, so the quality of electrical components will directly affect the reliability of the low-voltage power supply system.
The development of low-voltage electrical appliances depends on the needs of the development of the national economy and the development of modern industrial automation, as well as the research and application of new technologies, new processes, and new materials. The development of modularization, combination and generalization of components.
