The E-T-A 3120-N series circuit breaker/switch combination offers integral overcurrent protection and switching in a single component. This model, the 3120-F523-H7T1-W01D-X3120-U0203M-20A, is a 2-pole thermal circuit breaker with a 20A current rating and a 250V voltage rating.
Designed for reliability and cost-effectiveness, the 3120-N utilizes a bimetal strip tripping element that tolerates inrush current peaks and trips faster at high ambient temperatures. It eliminates the need for fuse replacement, as it can be easily reset after tripping. This reduces mounting and wiring time by consolidating the functions of a switch, fuse-holder, and blade fuses into one unit.
The breaker features a panel mount type and a rocker actuator with no illumination. It is approved by CSA, GB, IEC, and UL standards. The 3120-N series is known for its space-saving design and enhanced reliability due to fewer single components.
This specific part is compliant with RoHS3, has an MSL of 1, and is REACH unaffected. It is suitable for applications requiring reliable overcurrent protection and switching.
