3120-N321-P7T1-W02D-12A Description

Short technical summary and product information.

The E-T-A 3120-N Series thermal circuit breaker is a versatile component that combines overcurrent protection with an ON/OFF switch function. It utilizes a thermal-bimetal trip element, making it suitable for protecting motors, pumps, transformers, and cables from overloads. This 2-pole breaker is rated for 12A and features a panel mount design with a rocker actuator.

 

Designed for reliability and ease of use, the 3120-N Series can be easily and quickly reset after tripping. Its positively trip-free mechanism ensures reliable disconnection even if the actuator is blocked. The series offers voltage ratings of AC 240 V and DC 50 V, with AC 415 V available upon request. Typical applications include medical and laboratory equipment, apparatus and machine construction, professional tools, and household appliances.

 

This thermal circuit breaker is suitable for use in medical equipment according to IEC/EN 60601. It offers features such as optional push-in terminals for simplified wiring and expandable functionality through add-on modules for low voltage release, auxiliary contact, remote trip, or fast magnetic trip. The internal resistance for a 12A rating is typically less than 0.02 Ohm.
