Siemens 3RT2017-1AB01 Three-Phase AC Contactor

Siemens 3RT2017-1AB01 is a three‑pole power contactor in the S00 size, designed for AC-3e/AC-3 motor control with a 24 V AC coil. It performs up to 12 A and up to 5.5 kW at 400 V (50/60 Hz), enabling reliable starting and running of small to mid‑size three‑phase motors in industrial equipment. The contactor provides one normally open auxiliary contact (NO) for discrete control signaling, interlocking, or feedback to a control system, and uses screw terminals for secure field wiring. This module is part of Siemens’ SIRIUS 3RT family, known for compact footprint and robust switching, making it suitable for panel builders and machine builders integrating motor starters into control circuits. Typical applications include conveyors, pumps, fans, machine tools, and other equipment where a rugged 3‑pole motor starter with a simple control coil is desired. The 24 V AC coil operates on 50/60 Hz power, aligning with common plant control power supplies, and the unit’s S00 size keeps it compact enough to fit into standard control panels while delivering dependable performance in demanding environments.
