This E-T-A 3120-N series thermal circuit breaker combines overcurrent protection with an ON/OFF switch function. It is designed for overload protection of motors, pumps, transformers, and cables, featuring a resettable thermal-bimetal trip element. The breaker has a current rating of 0.5A and a voltage rating of 415V.
Key specifications include a single pole configuration, rocker actuator, and panel mount type. The device is suitable for various applications including medical and laboratory equipment, apparatus and machine construction, professional tools, and household appliances. It offers reliable disconnection even with a blocked actuator due to its positively trip-free mechanism.
Additional features mentioned in the datasheet include optional push-in terminals for easy wiring and expandable functionality with add-on modules for low voltage release, auxiliary contact, remote trip, or fast magnetic trip. The breaker is also suitable for medical equipment according to IEC/EN 60601.
This thermal circuit breaker is designed for maximum equipment availability through overload protection matched to loads and quick resettability. It contributes to reduced mounting and wiring time, space-saving design, and increased overall reliability.
