The E-T-A 3120-N series thermal circuit breaker is a single component 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 specific model, 3120-N351-P7T1-W02D-0.7A, is a two-pole device with a current rating of 700mA and a voltage rating of 415V AC. It features a panel mount design and a rocker actuator. The positively trip-free mechanism ensures reliable disconnection even with the actuator blocked.
Key features include a resettable design for quick and easy restoration of power after tripping. The series is also suitable for use in medical equipment according to IEC/EN 60601 standards, ensuring maximum equipment availability through overload protection matched with loads and quick resettability. Reduced mounting and wiring time are also benefits due to its space-saving design.
Typical applications for this series include medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, office machines, audio equipment, and machine tools.
