The E-T-A 3120-N521-N7T1-W01A-12A is a thermal circuit breaker and switch combination that provides reliable overcurrent protection. It is a double-pole unit with a 12A current rating and is suitable for panel mounting.
This circuit breaker operates with a voltage rating of 240 VAC or 50 VDC, as specified in the datasheet. The trip element is a bimetal, allowing for easy and quick resetting after tripping. The positively trip-free mechanism ensures reliable disconnection even when the actuator is blocked.
Typical applications for this series include medical and laboratory equipment, apparatus and machine construction, professional tools, and household appliances. The device is designed for overload protection of motors, pumps, transformers, and cables, ensuring maximum equipment availability through matched overload protection and quick resettability.
Features include a rocker actuator, panel mount capability, and approval by agencies such as CSA, UL, and VDE. The series is also available with optional features like push-in terminals for simplified wiring and expandable functionality through add-on modules.
