We carry a wide range of breaker manufacturers and amperage sizes including Challenger, Cutler Hammer, Federal Pacific, GE, ITE-Siemens, Square D, Westinghouse and Zinsco. They range in sizes from 10 amps to over 3000 amps.
Circuit breakers shut off electrical circuits when they become overwhelmed by a current. Breakers that can handle 600 volts or less are considered low voltage. Medium voltage breakers can handle up to 1,500 volts, and use different methods to break their circuits such as vacuum, air or SF6 gas. High voltage breakers are often used for outdoor electrical systems and can handle a minimum of 1,500 volts. In addition to the same methods used by medium voltage breakers, high voltage breakers can also use bulk oil and minimum oil. These breakers tend to use gas.
When you need to replace a circuit breaker, make sure that your new breaker has the same volt-amperes as the old breaker.
