Air circuit breakers interrupt connections to load circuits in order to ensure the normal operation of electrical equipment. They're particularly useful in areas that are prone to risks of explosion or fire. Unlike oil circuit breakers, air circuit breakers are open and operate under atmospheric pressure, making it easier to alter and refurbish as needed. Bay Power offers a selection of both refurbished and brand new air circuit breakers for low to medium voltage applications.
