2012年2月24日 · 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.

ACB is an electromechanical switching device on the range of 800A to 4000A which is used for protection of short circuit, overload, instantaneous and earth fault protection. Microprocessor based protection device are used for monitor and operation of overload, short circuit and earth fault relay in auto condition.

Air Circuit Breaker (ACB) is an electrical device used to provide Overcurrent and short-circuit protection for electric circuits over 800 Amps to 10K Amps. These are usually used in low voltage applications below 450V. We can find these systems in Distribution Panels (below 450V).

The ACB and CCB cartridge pressure switches from Danfoss are small disc type pressure controls for use in air conditioning systems. With the switches you can expect robust and reliable operation and a long service life.
