The E-T-A 3120-N series circuit breaker/switch combination offers integrated overcurrent protection and switching in a single component. This model, the 3120-F31A-H7T1-W12LY3-12A, is a thermal circuit breaker with a 12A current rating and a 250V voltage rating. It is designed for panel mounting and features a rocker actuator with white illumination at 115V.
This circuit breaker utilizes a bimetal trip element, providing optimal overload protection and tolerating inrush current peaks from motors, transformers, and magnetic valves. After tripping due to overcurrent, it can be easily reset, eliminating the need for fuse replacement. The design reduces mounting and wiring time by combining the functions of a switch and a fuse holder.
Key specifications include a single pole configuration, panel mount type, and compliance with CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077 standards. The RoHS status is listed as RoHS3 Compliant, and the Moisture Sensitivity Level (MSL) is 1.
