    MCB

    MCB即微型断路器,也叫小型断路器,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,主要用于线路和电器设备的过载和短路保护。

    MCB的工作原理

    • 当连续过电流流过小型断路器时,双金属条被加热并使其弯曲;
    • 双金属条的这种弯曲会释放机械闩锁,打开触点并关闭小型断路器,从而阻止电流流入电路;
    • 要重新启动电流,必须手动打开小型断路器。这种机制可以防止由于过电流或过载而引起的故障。

    MCB的类型

    • B型:通常适用于家庭应用。它们也可用于开关浪涌较低或不存在的轻型商业应用中。
    • C型:通常用于使用荧光照明、电动机等的商业和工业应用。
    • D型:通常用于可能会出现高浪涌电流的工业应用。示例包括大型电池充电系统、卷扬用电动机、变压器、X光机和一些放电照明类型。
