This E-T-A 3120-N series thermal circuit breaker combines overcurrent protection with the function of an ON/OFF switch in a single component. It features 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 current rating of 20A and voltage ratings of 415V AC and 50V DC. It is designed for panel mounting and features a rocker actuator. The breaker is approved by CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077.
Additional features include a red illumination indicator with a nominal voltage of 12V. The 3120-N series is also available with optional features such as push-in terminals, appliance inlet modules, low voltage release, auxiliary contact function, remote trip, or fast magnetic trip. It is suitable for use in medical equipment according to IEC/EN 60601.
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 mounting and wiring time.
