3120-F31A-H7T1-W12LY3-1A Description

Short technical summary and product information.

The E-T-A 3120-N series circuit breaker/switch combination offers integrated overcurrent protection and switching functionality in a single component. This model, the 3120-F31A-H7T1-W12LY3-1A, is a single-pole thermal circuit breaker rated for 1A and 250VAC/50VDC.

 

Designed for reliability and cost-effectiveness, it utilizes a bimetal trip element that tolerates inrush current peaks and trips faster at high ambient temperatures. After tripping due to overcurrent, it can be easily reset, eliminating the need for fuse replacement. This reduces mounting and wiring time, as well as planning and storage costs, by replacing a separate switch and fuse holder.

 

The breaker features a rocker actuator and is designed for panel mounting. It is approved by CSA, GB, IEC, and UL standards. The unit is RoHS3 compliant and has an MSL of 1.

 

This component is ideal for applications requiring reliable overcurrent protection and switching in a compact, space-saving design. Its ability to be reset after tripping enhances operational continuity and reduces maintenance.
