Air Blast Circuit Breaker Overview by Anish Kumar is a document available to read on EtoBox.
An air blast circuit breaker uses compressed air to extinguish the electric arc that forms when it opens its contacts during a fault. It works by separating its contacts to interrupt the current when a fault is detected, then directing a blast of compressed air to extinguish the arc. There are three main types - axial blast directs air along the arc path, cross blast directs it at right angles to split the arc, and radial blast also directs it radially. Air blast circuit breakers offer advantages over oil c
