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, making it suitable for overload protection of motors, pumps, transformers, and cables. The breaker can be easily and quickly reset after tripping.
Key electrical specifications include a voltage rating of 240 VAC and 50 VDC, with AC 415V available upon request. The current rating range is from 0.1 to 20A, with options up to 30A available for single-pole devices. This particular model is a 2-pole unit with a 20A current rating.
Designed for panel mounting with a rocker actuator, this circuit breaker is built for reliability and ease of use. It is suitable for various applications including medical and laboratory equipment, apparatus and machine construction, professional tools, and household appliances. The positively trip-free mechanism ensures reliable disconnection even when the actuator is blocked.
