Electrical Air Circuit Breaker Symbol

The symbol for a thermal fuse used in any electrical circuit diagram.

Electrical air circuit breaker symbol. It operates on the temperature rather than the current unless the current is sufficient to increase the temperature above the threshold point.

A thermal fuse is a temperature sensitive switch. 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. Definition air circuit breaker is a devised that is used for lt low tension electrical system i e 415 volt it is used to switch on off of power and provides over current short circuit protection. Available in svg png jpg dxf dwg formats. 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 is used in lt panels for switching protection of load from variousfaults.
