The E-T-A 3120-N series circuit breaker/switch combination, model 3120-F351-H7T1-W14DR4-20A, offers integrated overcurrent protection and switching functionality in a single component. This thermal circuit breaker is designed for panel mounting and features a two-pole configuration with a 20A current rating and a 250V AC voltage rating.
The breaker utilizes a bimetal trip element for reliable overload protection, which can tolerate inrush current peaks from motors and transformers. After tripping due to an overcurrent event, the 3120-N can be easily reset, eliminating the need for fuse replacement. The rocker actuator is illuminated in red, with a nominal illumination voltage of 185V.
This component is approved by CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077. It is designed to reduce mounting and wiring time, as well as planning and stocking expenses, by replacing separate switches and fuse holders. The space-saving design makes it suitable for constricted areas, enhancing overall product reliability by reducing potential sources of error.
