An air circuit breaker (ACB) is an electrical device that protects electric circuits from short circuits and overcurrents. The ACB is controlled by atmospheric pressure. The ACB is used in the switching and protection mechanisms of electrical systems. An air circuit breaker (ACB) is an electrical device that protects electric circuits against overcurrent and short circuits in the range of 800 to 10,000 amps. These are primarily used in low-voltage (less than 450V) applications. To deal with you, we have a well-trained workforce. We provide the highest level of service to our customers.
