An air circuit breaker (ACB) is an electrical device that prevents short circuits and overcurrents in electrical circuits. The air pressure regulates the ACB. The ACB is employed in electrical systems' switching and protection processes. An air circuit breaker (ACB) is an electrical device that protects electric circuits in the range of 800 to 10,000 amps from overcurrent and short circuits. Low-voltage (less than 450V) applications are the most common. We have well-trained personnel to deal with you. For more details please contact us! 8383950646
