MCCBs are intended to provide overcurrent protection for conductors and equipment by opening automatically before the current reaches a value and duration that will cause an excessive or dangerous temperature in conductors or conductor insulation. Additionally, these devices can serve as the main disconnecting means for a control panel. This protection pertains to low level overcurrent, and short-circuit current.
