3120-F31A-H7T1-W12LY3-5A Description

Short technical summary and product information.

The E-T-A 3120-F31A-H7T1-W12LY3-5A is a thermal circuit breaker from the 3120-N series, designed for reliable overcurrent protection and switching in a single component. This single-pole breaker has a current rating of 5A and a voltage rating of 250VAC.

 

It utilizes a bimetal strip tripping element, which offers optimal overload protection and tolerates inrush current peaks from motors and transformers. The trip time is dependent on the overcurrent's peak and duration, as well as ambient temperature. After tripping, the breaker can be easily reset, eliminating the need for fuse replacement.

 

The 3120-F31A-H7T1-W12LY3-5A features a rocker actuator and is designed for panel mounting. This design reduces mounting and wiring time by integrating the functions of a switch and a fuse holder. It also helps reduce planning and storage costs by replacing multiple components with a single, space-saving unit.

 

Approval agencies include CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077, ensuring compliance with various industry standards. The breaker is specified as RoHS3 Compliant, MSL 1 Unlimited, and REACH Unaffected.
