Air circuit breaker symbol.

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. Such kind of breakers is used in three phase systems in industries. 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. Plain break type air break circuit breaker.

Circuit breakers symbols for use in electrical pneumatic and hydraulic schematic diagrams. 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. Its primary function is to interrupt current flow after a fault is detected. Available in svg png jpg dxf dwg formats.

It connects three phases whenever there is an overload or short circuit in any phase the circuit breaker trips all three phases simultaneously. Unlike a fuse which operates once and then must be replaced a circuit breaker can be reset either manually or automatically to resume. Plain brake air circuit breakers are the simplest form of air breakers.
