Air Circuit Breaker Parts

Air circuit breaker is a switchgear device used to provide overcurrent and short circuit protection for circuits ranging from 800 amps to.

Air circuit breaker parts.

The working of air circuit breakers is similar to miniature circuit breakers. An air circuit breaker is a circuit operation breaker that operates in the air as an arc extinguishing medium at a given atmospheric pressure. 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. 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.

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. This circuit breaker increases the arc voltage by mainly three different ways. A circuit breaker in which the contacts open and close in the air at atmospheric pressure is defined as an air circuit breaker. Air circuit breaker acb air circuit breaker acb is an electrical protection device used for short circuit and overcurrent protection up to 15kv with amperes rating of 800a to 10ka.

The arc in the air circuit breaker runs in a mixture of nitrogen oxygen and copper vapour. The arc is hurried along the process by various components in the arc chute such as puffers blowout coils arc runners and arcing horns. It operates in air where air blast as an arc quenching medium at atmospheric pressure to protect the connected electric circuits. For interrupting arc it creates an arc voltage in excess of the supply voltage arc voltage is defined as the minimum voltage required maintaining the arc.
