The E-T-A 3120-F521-N7T1-W14FR4-2A is a thermal circuit breaker designed for overload protection of motors, pumps, transformers, and cables. It features a rocker actuator for panel mounting and includes red illumination.
This dual-pole circuit breaker has a current rating of 2A and is rated for 250V AC and 50V DC. It offers reliable switching behavior with a positively trip-free mechanism. The device is compliant with multiple international standards including CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077.
Key technical specifications include a typical internal resistance of 0.27 Ohm at 2A, a typical life of 30,000 operations at 1 x IN inductive load on AC 240V, and an operating ambient temperature range of -30 to 60 °C. The circuit breaker also features a dielectric strength of 3,000 VAC between poles and an insulation resistance greater than 100 MOhms at 500V DC.
Applications for this type of circuit breaker include medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, office machines, audio equipment, and machine tools. The part is classified as obsolete, with a direct substitute available.
