Air Circuit Breaker Electrical Symbol

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.

Air circuit breaker electrical symbol. A thermal fuse is a temperature sensitive switch. The symbol for a thermal fuse used in any electrical circuit diagram. It operates on the temperature rather than the current unless the current is sufficient to increase the temperature above the threshold point. 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 its primary function is to interrupt current flow after a fault is detected.

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. Circuit breakers symbols for use in electrical pneumatic and hydraulic schematic diagrams. Unlike a fuse which operates once and then must be replaced a circuit breaker can be reset either manually or automatically to resume.
