This E-T-A 3120-N series thermal circuit breaker, part number 3120-N521-P7T1-W19FG4-20A, offers combined overcurrent protection and ON/OFF switch functionality. It features a 2-pole configuration, a 20A current rating, and is suitable for AC 240V and DC 50V circuits. The breaker is designed for panel mounting and has a green rocker actuator.
Ideal for overload protection of motors, pumps, transformers, and cables, this thermal circuit breaker utilizes a bimetal trip element. It ensures reliable disconnection and can be easily reset after tripping. The positively trip-free mechanism guarantees circuit disconnection even with a blocked actuator. The unit is also suitable for use in medical equipment according to IEC/EN 60601 standards.
With a nominal illumination voltage of 230V, this component is approved by CSA, KTL, UL, and VDE. Its features contribute to maximum equipment availability through overload protection matched to loads and quick resettability, reducing mounting and wiring time while saving space.
