A miniature circuit breaker (MCB) is an advanced form of fuse switch that works on thermal magnetic principle and it automatically cuts off the electric supply under abnormal circumstances. One important and interesting thing about MCB miniature circuit breakers is that we don’t need manual readjustments to restart the electric circuit, as we do in the case of fuse switches, but we just need to turn on the switch again. You can buy the most reliable and most safe MCB miniature circuit breakers from PCP Electric for your final electric distribution for a safe electric environment for your electric, mechanical or electronic components. We have all kinds of MCBs that can be compatible with different phases and different current ranges. You can check all options and inquire about your specific requirement too.
