The circuit breaker is a type of electromagnetic device designed to protect electrical circuits from damage caused by excessive current flow. This particular model features a hydraulic delay mechanism, allowing for a specified time interval before it trips and disconnects the circuit in case of an overload or short circuit. It has an ampere rating of 8A and can handle alternating currents up to 600V AC, as well as direct currents up to 125V DC. The device is mounted on a lever panel for easy operation.
