This is a circuit breaker designed to protect electrical circuits from damage caused by overloads or short circuits. It features a magnetic (hydraulic delay) mechanism that provides a time delay before interrupting the circuit, allowing for the safe clearing of fault conditions. The device has a current rating of 10A and can handle both AC and DC voltages, with a maximum allowable voltage of 277V AC and 80V DC. It is intended for use in lever panel mount applications.
