Circuit Breakers

Circuit breakers perform 3 key functions: protection, switching, and monitoring. Circuit breakers are designed to “break” (discontinue) the flow of electricity to protect people and equipment when current reaches an unsafe level due to overload, short circuit, or other electrical faults. Different types of circuit breakers may include design features that provide ground fault and/or arc fault protection for residential use, or with metering and alarm functions, and remote on/off control for commercial and industrial use. We are your one source solution for all your circuit breaker and equipment needs. We have the broadest array of circuit breakers in the industry, including Square D circuit breakers for superior circuit protection, the legendary PowerPact molded case circuit breaker (MCCB), and high current MasterPact air circuit breakers (ACB). Our products deliver the reliability and performance you and your customers demand.
