Different Types of Air Circuit Breakers (ACBs) Based on Functionality

The choice of ACB type depends on several factors such as the interrupting capacity, ease of maintenance, system size, and operational requirements. For low- to medium-power systems, plain or magnetic blowout types may suffice, whereas arc chute and cross-blast types are suited for higher-capacity, industrial-grade applications. For environments where downtime is costly, draw-out ACBs offer the flexibility of quick replacement without a complete system shutdown.
