The E-T-A 3120-N321-P7T1-W02L-12A is a thermal circuit breaker and switch combination designed for reliable overload protection. It features a two-pole configuration and a rocker actuator, suitable for panel mounting.
This device offers a current rating of 12A and supports a voltage rating of 240 VAC or 50 VDC, with 415 VAC available upon request. The thermal trip element ensures protection against overcurrent conditions for motors, pumps, transformers, and cables. It is designed for easy and quick resetting after tripping, and its positively trip-free mechanism guarantees reliable disconnection even with a blocked actuator.
Typical applications include medical and laboratory equipment, apparatus and machine construction, professional tools, and household appliances. The 3120-N series is also available with optional features like push-in terminals, appliance inlet modules, low voltage release, auxiliary contacts, remote trip, or fast magnetic trip modules, enhancing its functionality and integration capabilities.
The breaker is rated for 240 VAC and 50 VDC. A 415 VAC rating is available upon request.
