MCCB Boxes are the devices, which are made as the integral inner supporting and enclosed housing.  These are apt for making, breaking and carrying the currents between distinct contacts under abnormal circuit condition and normal circuit condition. These can perform well in overload condition as well as short circuit condition. MCCB boxes are compact in their measure and are finer than breaker-based framework. MCCB Boxes can be Switched On again as well as Reset as needed. The said boxes are of advanced utility and give protection from thermal overload, ground fault condition, short circuit and others.
