50HZ MCB durable Miniature Electrical Circuit Breaker Switch
Product Description
Miniature circuit breaker has the characteristics of advanced structure, reliable performance, strong breaking capacity, beautiful appearance and small size. It is mainly used in places with AC 50 Hz or 60 Hz, rated voltage below 400 V and rated working current below 63 a. It can be used for lighting of office buildings, residential buildings and similar buildings, for overload and short circuit protection of distribution lines and equipment, and for infrequent on-off operation and conversion of lines. Mainly used in industrial, commercial, high-rise and residential and other places.
