In the realm of electrical engineering and circuitry, the 4 pole circuit breaker stands as a crucial component, offering protection and safety to electrical systems. This device, with its four terminals or poles, is designed to protect not only the three-phase power lines but also the neutral line, thus ensuring a comprehensive safeguard against potential electrical hazards.

    The 4 pole circuit breaker plays a pivotal role in safeguarding industrial and commercial buildings, where both three-phase and single-phase loads are present. Its ability to disconnect all conductors simultaneously, including the neutral conductor, is particularly advantageous in scenarios where a fault in one phase could potentially affect the others. By tripping and interrupting the flow of current, the circuit breaker helps prevent damage to equipment and potential harm to personnel.
