3120-N31A-H7T1-W12LY3-2A Description

Short technical summary and product information.

The E-T-A 3120-N31A-H7T1-W12LY3-2A 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. After tripping, it can be easily and quickly reset.

 

This single-pole breaker has a current rating of 2A and a voltage rating of 415V. It is designed for panel mounting and features a rocker actuator. The illumination is white with a nominal voltage of 115V. The internal resistance per pole is less than 0.02 Ohm.

 

Typical applications for this type of circuit breaker include medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, office machines, and audio equipment. It is approved by CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077.

 

The device is designed for reliable disconnection even with the actuator blocked, ensuring maximum equipment availability through overload protection matched to loads and quick resettability. It offers reduced mounting and wiring time due to its space-saving design.
