MCB: Working Principle, Functions, Types, and Advantages Explained
WebSep 27, 2024 · MCB is an automatically operated electromechanical switch that is specially designed to protect an electrical circuit from damage caused by the excess current in case of an overload or short circuit condition. The basic function of MCB is to interrupt current flow in the circuit after a fault is detected. WebThe structure of the MCB is basic and safe, and it does not require any maintenance or inspections. The MCCB, on the other hand, is designed with numerous new parts and must be adequately serviced and examined. As a result, MCBs are not appropriate for applications that need frequent short circuit disruption.
