This E-T-A 3120-N series thermal circuit breaker, part number 3120-N501-N7Q1-W19AG4-20A, offers combined overcurrent protection and ON/OFF switch functionality. It is designed for overload protection of motors, pumps, transformers, and cables, with a trip element based on a thermal bimetal.
The breaker operates at AC 240V and DC 50V, with AC 415V available upon request. It has a current rating of 20A and features a 2-pole configuration. The actuator type is a rocker, and it includes green illumination for the nominal voltage of 230V. Mounting is achieved via a panel mount configuration.
Key features include a positively trip-free mechanism for reliable disconnection, quick and easy resettability after tripping, and suitability for medical equipment according to IEC/EN 60601. The internal resistance per pole is less than 0.02 Ohm. Typical life for a 2-pole configuration is 50,000 cycles at 1 x IN, inductive.
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. It is RoHS3 compliant.
