Air circuit breaker symbol.

The air circuit breakers are mostly of three types and are widely used for maintaining the indoor medium voltage and switch gears of the home. Circuit breakers symbols for use in electrical pneumatic and hydraulic schematic diagrams. An air circuit breaker also known as an air blast circuit breaker or acb is an automatically operated electrical switch that uses air to protect an electrical circuit from damage caused by excess current from an overload or short circuit. This symbol represents circuit breaker with three poles.

Unlike a fuse which operates once and then must be replaced a circuit breaker can be reset either manually or automatically to resume. It connects three phases whenever there is an overload or short circuit in any phase the circuit breaker trips all three phases simultaneously. Its primary function is to interrupt current flow after a fault is detected. Plain break type air break circuit breaker.

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. It operates in air where air blast as an arc quenching medium at atmospheric pressure to protect the connected electric circuits. 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.
