Air Circuit Breaker - Principle of Air Circuit Breaker - Types of Air Circuit Breaker


The type of circuit breakers, which operates in air at atmospheric pressure, is understood to be an Air breaker. Air breaker has fully replaced by oil breaker. In several countries, still it's a preferred option to use an Air circuit breaker up to 15 Kilo Volt as a result of, there's no probability of oil fire like in oil circuit breaker.

Air breaker may be a device wont to give over current and short circuit Protection for circuits starting from 800 Amps to ten thousand Amps. One mustn't be confused between Air breaker and Air Blast breaker. Air Circuit Breakers are typically used in low voltage applications below 450 volts.





The working principle of Air circuit breaker is quite totally different from alternative varieties of circuit breaker. the most aim of circuit breaker is to prevent reestablishment of arcing after current zero wherever the contact gap can stand up to the system recovery voltage. It wills it same work; however in a totally different manner. throughout interruption of arc, it creates an arc voltage rather than provide voltage. Arc voltage is outlined because the minimum voltage needed for maintaining arc.


Types of Air circuit breaker.

1. Plain air circuit breaker or Cross-Blast Air circuit breaker. 
2. Air blast circuit break..
