The Air Circuit Breaker (ACB) is a vital component in electrical distribution systems, offering crucial protection and control for various applications. Designed to protect electrical circuits from overloads and short circuits, ACBs play an indispensable role in maintaining the safety and efficiency of power systems.

    At its core, an ACB functions by automatically disconnecting the circuit when it detects conditions that could lead to damage or danger. This disconnection occurs when the current exceeds a predefined threshold, typically caused by faults or excessive load. The ACB effectively isolates the affected circuit, preventing potential damage to electrical equipment and minimizing the risk of fire or other hazards.
