A circuit breaker is a safety device that is used in an electrical panel. It is an electrical device that is available in a variety of sizes and that monitors and controls the amount of amps that are being sent through the electrical wiring. In the event of a power surge in the electrical wiring, a breaker, which is initially in an "on" state, will go to an "off" state and shut down the electrical power leading from that breaker. This can prevent a fire from starting on an overloaded circuit or prevent the destruction of the device drawing the electricity.Types of full circuit breaker selection from several manufacturers when looking for a DC circuit breaker, main circuit breaker, fuse box circuit breaker, 12 volt circuit breaker, resettable circuit breaker, thermal circuit breaker, auto circuit breaker or any types of circuit breakers for residential, commercial, industrial and scientific applications.
