miniature circuit breakers can be used for overload and short-circuit protection of lighting, distribution lines and equipment in office buildings, residences and similar buildings, and can also be used for infrequent on-off operations and conversions of lines. It is mainly used in various places such as industrial, commercial, high-rise and residential buildings.

miniature circuit breakers have the characteristics of advanced structure, reliable performance, strong breaking capacity, beautiful and compact appearance, etc. They are mainly used in places with AC 50HZ or 60HZ, rated voltage below 400V, and rated working current below 63A.

Miniature circuit breakers are used for single-phase and three-phase short-circuit, overload, and overvoltage protection below 125A, including single-pole 1P, two-pole 2P, three-pole 3P, and four-pole 4P.

Miniature circuit breakers are suitable for overload and short circuit protection of AC 50/60Hz rated voltage 230/400V, rated current up to 63A lines, and can also be used for infrequent operation conversion of lines under normal conditions. Miniature circuit breakers are mainly used in various places such as industrial, commercial, high-rise and residential buildings.

Molded case circuit breakers can automatically turn off the current after the current exceeds the trigger setting.

Molded case circuit breakers are mostly operated manually, and electrical switching can be chosen for high power.
