Introduction of Moulded Case Circuit Breaker (MCCB)

Moulded Case Circuit Breakers. A circuit breaker having a supporting housing of moulded insulating material forming an integral part of the circuit breaker. In the circuit breakers also, the current flows through the thermally delayed bimetallic release. A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and interrupt current flow. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city.

KA Ratings

Under fault conditions (such as a short circuit) much more current flows through the circuit than what it was designed for. A circuit that was designed for a maximum of 20A may suddenly be drawing hundreds, if not thousands of amps. The circuit breaker will trip if this occurs.

However, what if during a short circuit there is more current flowing through the circuit than the kA rating of the circuit breaker? In this case the circuit breaker will fail, often in either one of two ways. One possibility is that the contacts in the circuit breaker will weld, thus preventing the circuit breaker from tripping. The best case scenario for this is that the cable in the circuit is damaged. The worst case is that a fire is started. Another possibility is that the circuit breaker explodes, as a result of the copper in the circuit breaker overheating and turning into dangerous plasma. This could be very dangerous to people nearby, for example the electrician turning the circuit breaker on after a fault.

Breaking Capacity

A molded case circuit breaker is probably  the most common  is use for residential use and low voltage applications  in industrial settings,Breaking capacity or interrupting capacity is the current that a fuse, circuit breaker, or other electrical apparatus is able to interrupt without being destroyed or causing an electric arc with unacceptable duration. The prospective short circuit current which can occur undershort circuit conditions should not exceed the rated breaking capacity of the apparatus.
