The E-T-A 3120-N321-P7T1-W12DY3-12A is a two-pole thermal circuit breaker that combines overcurrent protection with the function of an ON/OFF switch. It utilizes a thermal-bimetal trip element and is suitable for overload protection of motors, pumps, transformers, and cables.
This circuit breaker has a current rating of 12A and a voltage rating of 415V. It features a panel mount design with a rocker actuator and white illumination at 115V. The internal resistance per pole is less than 0.02 Ohm.
Designed for reliability and ease of use, the 3120-N series can be easily and quickly reset after tripping. The positively trip-free mechanism ensures reliable disconnection even with the actuator blocked. It is approved by CSA, GB, IEC, and UL standards.
Typical applications include medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, office machines, audio equipment, and machine tools.
