There are several types of air circuit breakers and switching gears available in the market today that is durable high performing easy to install and maintain. Such breakers are used for low voltages generally up to 15kv and rupturing capacities of 500mva. A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit its basic function is to interrupt current flow after a fault is detected. The arc in the air circuit breaker runs in a mixture of nitrogen oxygen and copper vapour.

What is air circuit breaker. When this happens an arc will appear between the. An air circuit breaker is a circuit operation breaker that operates in the air as an arc extinguishing medium at a given atmospheric pressure. Air circuit breaker acb air circuit breaker acb is an electrical protection device used for short circuit and overcurrent protection up to 15kv with amperes rating of 800a to 10ka.

It operates in air where air blast as an arc quenching medium at atmospheric pressure to protect the connected electric circuits. Unlike a fuse which operates once and then must be replaced a circuit breaker can be reset either manually or automatically to resume.
