The circuit breaker is a type of magnetic device designed to interrupt electrical circuits in the event of an overload or short circuit. It features a hydraulic delay mechanism, ensuring that the circuit is fully disconnected before the system resets. This 19-ampere unit is suitable for use with AC power supplies up to 250 volts and DC supplies up to 80 volts. The lever allows for manual control over the circuit, while its panel-mount design facilitates easy installation in a variety of applications.
