The E-T-A 3120-N311-P7T1-W14FR1-3A is a single-pole thermal circuit breaker that combines overcurrent protection with an ON/OFF switch function. It utilizes a bimetal trip element for reliable overload protection of motors, pumps, transformers, and cables. This device can be easily and quickly reset after tripping.
Key electrical specifications include a voltage rating of 240V AC / 50V DC (with AC 415V available upon request) and a current rating range from 0.1A to 20A, with this specific model rated at 3A. The internal resistance for the 3A rating is 0.0595Ω. The typical life expectancy is rated for 30,000 cycles at 1x IN under inductive load conditions at 240V AC.
Designed for panel mounting, this circuit breaker features a rocker actuator and red illumination. It is approved by CSA, GB, IEC, and UL standards. The device is suitable for various applications including medical and laboratory equipment, apparatus and machine construction, professional tools, and household appliances.
