3120-F521-P7T1-W02D-3A Description

Short technical summary and product information.

The E-T-A 3120-F521-P7T1-W02D-3A is a thermal circuit breaker that combines ON/OFF switching with integral overcurrent protection, conforming to S-type TO CBE to EN/IEC 60934 standards. Its trip element is bimetal, making it suitable for overload protection of motors, pumps, transformers, and cables.

 

This model features a 3A current rating and a 250V voltage rating. It is designed for panel mounting and has a rocker actuator. The circuit breaker is single pole and double pole versions are available. It offers reliable switching behavior due to its positively trip-free mechanism and convenient snap-in mounting.

 

Typical applications include medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, office machines, audio equipment, and machine tools. Options such as illumination, water splash protection, auxiliary contacts, and various trip types are available for customization.

 

Key technical data includes a rated voltage of AC 240V and DC 50V, with a current rating range from 0.1 to 20A. The typical life for 1-pole operation at 1x IN inductive is 30,000 operations. The operating temperature range is -30 to 60°C.
