3120-N521-P7T1-W19DG3-2A Description

Short technical summary and product information.

The E-T-A 3120-N521-P7T1-W19DG3-2A is a thermal circuit breaker that combines overcurrent protection with an ON/OFF switch function. It utilizes a bimetal trip element for reliable operation.

 

This 2-pole breaker is rated for 2A and operates at 240V AC, with DC 50V and AC 415V also specified in the datasheet. It features a panel mount design with a green rocker actuator, suitable for 115V illumination.

 

Ideal for overload protection of motors, pumps, transformers, and cables, this circuit breaker can be easily and quickly reset after tripping. Its positively trip-free mechanism ensures reliable disconnection even with a blocked actuator. The series is also suitable for use in medical equipment according to IEC/EN 60601.

 

Applications include medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, office machines, audio equipment, and machine tools.
