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, which provides a time lag between the trip point and the actual disconnection of power. This allows for the safe shutdown of equipment in case of an overload. The device has an ampere rating of 1.5A and can handle voltages up to 250V AC or 80V DC. It is typically mounted on a lever panel for easy access and operation.
