This product is a circuit breaker designed for use in electrical systems that operate at high voltage levels. It has a magnetic and hydraulic delay mechanism, allowing it to trip after a short time when an overload condition is detected. The breaker can handle currents up to 50A and can be used with alternating current (AC) or direct current (DC) power supplies of 480V AC and 125V DC respectively. It features a toggle switch for easy operation and is designed to be mounted on a panel in the electrical system.
