  A miniature circuit breaker (MCB) is an Electrical Switch that automatically switches off the electrical circuit during an abnormal network condition, resulting in overload and faulty conditions. We use an MCB in a low voltage electrical network instead of a fuse. Earlier, we protected against over-current by using fuse wire (indeed, we used to sell it!). The principle was pretty simple - over-current would quite literally 'blow' the fuse wire by rapidly heating and melting it, thus breaking the electrical connection and, in doing so, protecting the rest of the electrical circuit. Working & Operation of MCB Under normal working conditions, MCB operates as a switch (manual one) to make the circuit ON or OFF. However, under overload or short circuit conditions, it automatically works or trips so that current interruption occurs in the load circuit. The visual indication of this trip observes by automatic movement of the operating knob to OFF position. This automatic operat
