The E-T-A 3120-N321-P7T1-W02X-12A is a thermal circuit breaker that combines overcurrent protection with an ON/OFF switch function. It utilizes a thermal-bimetal trip element for reliable overload protection of motors, pumps, transformers, and cables. This 2-pole device is designed for panel mounting and offers a current rating of 12A with a voltage rating of up to 415V AC.
This circuit breaker is suitable for various applications including medical and laboratory equipment, apparatus and machine construction, professional tools, and household appliances. It can be easily and quickly reset after tripping, and its positively trip-free mechanism ensures reliable disconnection even when the actuator is blocked. The device supports AC 240V and DC 50V, with AC 415V available upon request.
Key features include its dual functionality as a breaker and switch, panel mount design, and rocker actuator. The series is also available with optional features like push-in terminals for simplified wiring and expandable functionality through add-on modules.
