The E-T-A 3120-N311-P7T1-W19DG4-3A is a single-pole thermal circuit breaker that combines overcurrent protection with the function of an ON/OFF switch. It utilizes a thermal bimetal trip element and is suitable for overload protection of motors, pumps, transformers, and cables. The breaker can be easily and quickly reset after tripping, and its positively trip-free mechanism ensures reliable disconnection.
Key electrical specifications include a voltage rating of 415V AC and a current rating of 3A. It is designed for panel mounting and features a rocker actuator. The illumination is green with a nominal voltage of 230V. The device is approved by CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077.
This thermal circuit breaker is well-suited for applications in medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, office machines, audio equipment, and machine tools. Its design ensures maximum equipment availability through overload protection matched to loads and quick resettability, reducing mounting and wiring time.
