The thermal circuit breaker/switch combination that provides overcurrent protection and the functionality of an ON/OFF switch in a single component. It features a thermal bimetal trip element and is ideal for overload protection in applications such as motors, pumps, transformers, and cables. The trip-free mechanism ensures reliable disconnection of the circuit even when the actuator is blocked. With voltage ratings of AC 240V and DC 50V, this circuit breaker is perfectly matched with the loads, preventing nuisance tripping. It has a current rating range of 0.1A to 20A, with an optional range of up to 30A. The compact design of this circuit breaker saves space and reduces mounting and wiring time, making it a reliable choice for various applications.
