The E-T-A 3120-N series, represented by the 3120-F32K-P7T1-W02Q-12A, is a thermal circuit breaker designed for both protection and switching functions in a single component. This device utilizes a bimetal strip tripping element for reliable overload protection, capable of tolerating inrush current peaks from motors and transformers.
Key electrical specifications include a current rating of 12A, an AC voltage rating of 250V, and a DC voltage rating of 50V. It is a double-pole breaker with a rocker actuator and no illumination. The breaker type is thermal, offering advantages such as faster tripping at high ambient temperatures.
Designed for panel mounting, this circuit breaker eliminates the need for separate fuses and fuse holders, reducing mounting and wiring time, as well as planning and storage costs. Its space-saving design enhances reliability by minimizing potential sources of error. The 3120-N series is approved by CSA, GB, IEC, and UL standards.
