Siemens 3RF2310-1AA44 Three-Phase Industrial Contactor

Siemens 3RF2310-1AA44 is a solid-state (SSR) single‑phase contactor in the 3RF2 family that switches an AC load. It supports a main circuit voltage range of 48–460 VAC and a continuous current rating of 10 A, with a control input of 4–30 V DC. The device uses screw terminals for both the main connections and the control input, simplifying wiring in control cabinets. Designed for environments up to 40°C ambient, this 1‑phase 3RF2 solid‑state relay is intended for compact automation applications where rapid, wear‑free switching is advantageous. As the 1AA44 variant, it is explicitly marketed by Siemens as a single‑phase SSR with a 10 A load rating, part of the broader 3RF2310‑1AA family.
