Siemens 3RT2015-1AB02 Three-Phase Power Contactor

Siemens 3RT2015-1AB02 is a three‑pole S00‑size SIRIUS power contactor (3RT2 family) designed for AC‑3e/AC‑3 duty. It operates from a 24 V AC coil (50/60 Hz) and switches motor loads up to 7 A, delivering up to 3 kW at 400 V in a compact, screw‑terminal package. The unit includes one normally closed auxiliary contact and an auxiliary switch block, making it suitable for basic motor control and interlocking in control panels. It carries a main/auxiliary insulation rating of 690 V and an coil‑to‑main isolation rating of 400 V, with surge withstand of 6 kV on both circuits. Built for rugged panel use, it supports ambient operating temperatures from -25 to +60 °C and is rated for up to 2,000 m elevation, with a broad humidity range. Weight is approximately 231 g, and the 3RT2015‑1AB02 is compatible with standard Siemens control gear and applies to compact motor starter applications in 400 V networks. This model is part of Siemens’ industry‑standard 3RT2 lineup, offering reliable switching for AC motors in space‑conscious installations, such as small conveyors, fans, pumps, and other light to medium‑duty loads that fall under AC‑3e/AC‑3 ratings.
