About Circuit Breakers and Accessories

Circuit breakers are a critical component of electrical systems, protecting them against overload or short-circuiting. These devices shut off power when levels exceed a safety threshold in order to prevent damage to equipment or personnel. There are a variety of types of circuit breakers to suit different applications, including miniature, molded case, low voltage, GFCI, and AFCI. Circuit breaker accessories are used to extend the functionality, mount, secure, protect, and extend the life of circuit breakers.
