3120-N321-P7T1-W12FY4-5A Description

Short technical summary and product information.

The E-T-A 3120-N321-P7T1-W12FY4-5A is a thermal circuit breaker 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 2-pole breaker has a current rating of 5A and a voltage rating of 415V.

 

Designed for panel mounting with a rocker actuator, this circuit breaker offers features such as white illumination at 230V. It is built to ensure maximum equipment availability through overload protection matched with loads and quick resettability. The positively trip-free mechanism ensures reliable disconnection even with a blocked actuator.

 

Typical applications include medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, office machines, audio equipment, and machine tools. It is approved by CSA, GB, IEC, and UL standards.
