Circuit breakers are one of the most important devices that we have in our homes and businesses. They are responsible for protecting a circuit from damage due to an overload or short in a circuit by limiting or interrupting the flow (current) of electricity (amperage). If too much current is flowing, they are designed to trip (interrupt the current) and to protect from overheating until a qualified person can evaluate the problem. Circuit breakers provide a great deal of safety and prevent damaging electrical fires. The NFPA (National Fire Protection Association) is the association that creates and maintains codes and regulations of electrical standards and codes. For more information, please see www.nfpa.org.
We offer circuit breakers for many applications including residential, commercial and industrial applications. We sell obsolete products from as far back as the 1960s as well as new and refurbished products that are still currently in production today. We deal in 600 volts AC or less and amperages ranging from 15 to 4000 amperes.
