This is a circuit breaker designed to protect electrical circuits from overload or short circuits. It has a magnetic release mechanism with hydraulic delay, which means it will take a little time before the breaker trips in case of an overload. This unit operates at 25 amperes and can handle either AC (alternating current) or DC (direct current) voltage up to 250 volts AC or 150 volts DC. It features a lever that is mounted on a panel for easy operation.
