    Tips: What is a miniature circuit breaker?
    Miniature circuit breaker (MCB), also known as micro circuit breaker, is mainly used for alternating current 50Hz or 60Hz and the workplace below rated voltage 480/277V and rated current 63A. Miniature circuit breaker that has the features including advanced structure, reliable performance, strong breaking capacity, well designed shape and small size, is suitable for lighting of office buildings, houses and similar buildings, overload of distribution line and equipment, and short circuit protection, as well as, infrequent switch on-off operation and conversion.
    Miniature circuit breaker is commonly used to connect and break the circuit by separating the moving contact and the fixed contact of miniature circuit breaker. When the miniature circuit breaker is switched on, the moving contact and the fixed contacts are closed under the opposite mechanical motion.
