Diagram Air Circuit Breaker Parts Name

It operates in air where air blast as an arc quenching medium at atmospheric pressure to protect the connected electric circuits.

Diagram air circuit breaker parts name.

The arc in the air circuit breaker runs in a mixture of nitrogen oxygen and copper vapour. What is air circuit breaker. Such breakers are used for low voltages generally up to 15kv and rupturing capacities of 500mva. When the current is greater than 100a these gases get dissociated into atoms which changes the characteristics of the arc on account of the associated change in its thermal conductivity.

When this happens an arc will appear between the. 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. An air circuit breaker is a circuit operation breaker that operates in the air as an arc extinguishing medium at a given atmospheric pressure. Air circuit breaker has several advantages over the oil as an arc quenching medium.

There are several types of air circuit breakers and switching gears available in the market today that is durable high performing easy to install and maintain. 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.
