Air Circuit Breaker

For circuit breaker systems in power distribution applications, air circuit breakers are among the most critical components for protecting electrical systems from overloads and short circuits. Air circuit breakers use air as the arc-extinguishing medium to interrupt fault currents and provide reliable overcurrent protection in medium to high-amperage applications. Electrical.com carries an extensive selection of air circuit breakers from all major manufacturers, including new, used, surplus, and re-certified options. These components are designed to meet the diverse needs of industrial facilities, commercial buildings, power generation plants, and critical infrastructure applications.
