The E-T-A 3120-N series thermal circuit breaker is a single-pole device that combines overcurrent protection with the functionality of an ON/OFF switch. It utilizes a thermal-bimetal trip element, making it suitable for overload protection of motors, pumps, transformers, and cables.
This circuit breaker features a current rating of 2A and can handle AC voltage up to 415V and DC voltage up to 50V. It is designed for panel mounting and has a rocker actuator. The device is approved by CSA, GB, IEC, and UL standards.
Key features include a positively trip-free mechanism for reliable disconnection, even with a blocked actuator. It is also suitable for use in medical equipment according to IEC/EN 60601. The design aims to ensure maximum equipment availability through overload protection matched to loads and quick resettability, reducing nuisance tripping.
Typical applications for the 3120-N series include medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, office machines, audio equipment, and machine tools.
