The Air Circuit Breaker is a Switchgear Device Use to Provide Overcurrent and Short Circuit Protection for Circuits Ranging from 800 AMPS to 10000 AMPS.

　　

　　

　　One Should Not Be Confused Between Air Circuit Breaker and Air Blast Circuit Breaker.

　　Air Circuit Breakers are usually used in Low Voltage Applications Below 450 Volts. You can Today Find These in Distribution Panels (Below 450 Volts).

　　

　　We have always discussed the working of the circuit breaker in another article. In this section, we will discuss the working of the AirCuit Breaker.

　　

　　When the circuit breaker is bebing Opened, the main controls open first and during the Opening of Main Contorys the Arcing Contracts Are Still in Touch Each Other.

　　As the current gets. A paradlel Low Resistive Path Through the Arcing Contory During During The Opening of Main Contorys. TheRe Will even arcent in the main contal.

　　

　　The arc is queenched food during the current zero.

　　

The Electrically Operating Motor is using to operate the spring charging means for closing and opening the circuit breaker.

ACB BREAKER FIXED TYPE The Power Supply Could Be ACB BREAKER FIXED TYPE SINGLE-PHASE 230V AC SUPPLY Or Low Voltage 24V-110V DC SUPPLY FORING No Availivity.
