The E-T-A 3120-N323-P7T1-W19LG3-20A is a thermal circuit breaker that combines overcurrent protection with the function of an ON/OFF switch. It utilizes a bimetal trip element for reliable operation.
This 2-pole breaker is rated for 20A current and can handle up to 240V AC or 50V DC (with AC 415V available upon request). It features a panel mount design with a rocker actuator and green illumination at 115V nominal.
Typical applications include overload protection for motors, pumps, transformers, and cables in medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, office machines, and audio equipment. The positively trip-free mechanism ensures reliable disconnection even with the actuator blocked, and it can be easily and quickly reset after tripping.
Compliance includes RoHS3, REACH Unaffected, and MSL 1. Approval agencies include CSA, KTL, UL, and VDE.
