Siemens 3RT2015-1AR61 is a compact three-pole power contactor in the SIRIUS 3RT2 family designed for AC-3e/AC-3 motor control. It is rated up to 7 A and 3 kW at 400 V AC for 50 Hz; for 60 Hz operation it covers 400–440 V, aligning with typical 400 V three‑phase systems. The unit comprises three poles and includes a single normally open auxiliary contact; it uses screw terminals for main and auxiliary connections and is sized as S00. Ideal for panel-mounted motor control in 400 V systems, it supports reliable disconnection of all three lines in applications such as conveyors, pumps, and fans in automation environments where AC-3 duty is required.
