The 4 pole automatic circuit breaker (ACB) stands as a pivotal component in the realm of electrical engineering, ensuring seamless power transition and reliability in various industrial and domestic settings. This sophisticated device, with its four poles, effectively manages the flow of electricity, safeguarding electrical systems from potential hazards.

    The core functionality of the 4 pole ACB lies in its ability to seamlessly switch between two power sources. Typically, it operates in tandem with a primary power source, such as utility grid electricity, and a backup source, often a generator. When the primary source remains operational, the ACB maintains a steady supply to the connected load. However, in the event of a power outage or fault in the primary source, the 4 pole ACB springs into action, rapidly transferring the load to the backup source. This transition, occurring within milliseconds, is crucial in maintaining the continuity of power supply, ensuring minimal disruption to critical operations.
