Before the 1980s, vacuum circuit breakers were in the initial stage of development. Technically, people were constantly exploring and not being able to formulate technical standards until the relevant product standards were established after 1985. Its rated current reaches 5000A, the breaking current reaches a good level of 50kA, and has been developed to a voltage level of 35kV.
The miniature circuit breaker has the characteristics of advanced structure, reliable performance, strong breaking capacity and beautiful appearance. It is mainly used for places with AC 50HZ or 60HZ, rated voltage below 400V, and rated working current below 63A. It can be used for overloading and short-circuit protection of distribution lines and equipment in office buildings, lighting of residential buildings and similar buildings. It can also be used for infrequent on-off operation and conversion of lines.
The internationally recognized high-voltage and low-voltage electrical appliances have a boundary voltage of 1000V (1500V for DC). Above AC 1000V is a high-voltage electrical appliance, and 1000V and less than 1000V is a low-voltage electrical appliance. Sometimes transformers are also included in high-voltage electrical appliances.
