ACB - AIR CIRCUIT BREAKER is a breaker for the purpose of protecting low voltage circuit. It is an electronic equipment that is used for protection of electric circuits from short circuits or overcurrent. Generally, a circuit breaker switches or protects the system. The applications of circuit breakers mainly include power systems, and it operates at an atmospheric pressure in air. In case, where the appliances and instruments are more frequently utilized and operated with a heavy power supply and/or high voltage, it becomes compulsory to protect the machines from the excess flow of the current. This is done to avoid the possible damage to the plant which may be caused due to the high voltage. SE India offers a range of elevated unique ACB that are quite capable to handle electric overflow and any issues of high voltage. The protection of electric circuits over 800 Amps to 10k Amps is the principal purpose of the air circuit breakers. SE has presented an eminent solution to overcome the issues of high voltages at large.
