Air Breaker Switch. It operates in air where air blast as an arc quenching medium at atmospheric pressure to protect the connected electric circuits. An electric switch in which the opening and closing of contacts and extinguishing of the electric arc are accomplished by means of compressed air.
This guide walks you through different types of circuit breakers to help you choose which is best for your home s electrical needs. An electric switch in which the opening and closing of contacts and extinguishing of the electric arc are accomplished by means of compressed air. Air break switches abs are widely installed throughout distribution networks for use as both isolation or switching points.
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.
The most widely used pressures are 1 6 to 4 mn m2 16 to 40 atm. The air pressure in an air break switch ranges from 0 4 to 6 meganewtons per sq m mn m2 or 4 to 60 atmospheres atm. The most widely used pressures are 1 6 to 4 mn m2 16 to 40 atm. The air break switch is mostly installed in the distribution network as a switching point.
