circuit breaker has the characteristics of advanced structure, reliable performance, strong breaking capacity, beautiful appearance and small size. It is mainly used in places where AC 50HZ or 60HZ, rated voltage below 400V, and rated working current below 63A. It is used for the overload and short circuit protection of lighting, power distribution lines and equipment in office buildings, residences and similar buildings. It can also be used for infrequent on-off operations and conversion of lines. mcb 1 amp circuit breaker is mainly used in various places such as industry, commerce, high-rise and residential buildings.
Molded Case Mcb 1 Amp Circuit Breaker-MCCB
It can automatically cut off the current after the current exceeds the trip setting. Molded case circuit breakers usually contain thermal and magnetic trip units, while large models of molded case circuit breakers are equipped with solid state trip sensors. The trip unit is divided into: thermal magnetic trip and electronic trip.
It is also called a device-type circuit breaker, because the outer contact of the grounding wire terminal, the arc extinguishing chamber, the trip unit and the operating mechanism are all installed in a plastic shell. Auxiliary contacts, undervoltage releases and shunt releases are mostly modularized, with very compact structure, and maintenance is generally not considered, and it is suitable for protection switches for branch circuits.
