Circuit Breakers and Accessories

Circuit breakers are automatic switches that protect your power systems from potential damage caused by short circuits or overloads. Circuit breakers shut off your power when the levels get too high to prevent further and more dangerous damage to your building and system. Graybar has a wide variety of circuit breakers for any size power system or configurations of electrical systems. Our collection includes QO circuit breakers, homeline circuit breakers, circuit breaker enclosures and molded case circuit breakers.
