微型断路器，简称MCB（Micro Circuit Breaker/ Miniature Circuit Breaker），是建筑电气终端配电装置引中使用最广泛的一种终端保护电器。 用于125A以下的单相、 三相 的短路、过载、过压等保护，包括单极1P，二极2P、三极3P、四极4P等四种。

1.MCB是miniature circuit breake的缩写即微型断路器，中文简称微断 2.63A代表框架电流，即此断路器触头容量最大能承受63A的电流. 3.3P是3pole即三极的缩写，即用于三相回路。

UL489 miniature circuit breakers (MCBs) ensure electrical safety in multiple applications. UL489 MCBs feature two different tripping mechanisms, the delayed thermal tripping mechanism for overload protection, and the magnetic tripping mechanism for short circuit protection.
