The circuit breaker is a switch designed to interrupt the flow of electrical current in the event of an overload or short circuit. It has a rating of 50 amps at 480 volts AC and 125 volts DC, making it suitable for use in industrial or commercial settings where high-voltage equipment is present. This type of circuit breaker typically features a lever-operated mechanism that allows users to manually trip the switch and reset it when necessary. The panel mount design enables easy installation into electrical panels, providing a secure connection point for wiring.
