About Circuit Breakers

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.
