This E-T-A 3120-N series thermal circuit breaker combines overcurrent protection with an ON/OFF switch function in a single component. It utilizes a thermal-bimetal trip element, making it suitable for overload protection of motors, pumps, transformers, and cables. The breaker can be easily and quickly reset after tripping.
Key electrical specifications include a 415V AC voltage rating and a 3A current rating. It is a single-pole device with a panel mount type and a rocker actuator. The internal resistance per pole is 0.0595 Ohm. Approvals include CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077.
Typical applications for this thermal circuit breaker include 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 nuisance tripping.
