Siemens 3RT2017-1AB01 Contactor

Siemens 3RT2017-1AB01 is a compact 3-pole power contactor in the S00 size designed for AC-3 and AC-3e duty, featuring three normally open main contacts that switch up to 12 A and handle a load of up to 5.5 kW at 400 V. The coil operates at 24 V AC with a 50/60 Hz supply, allowing straightforward control from standard 24 V automation circuits, and the unit includes one normally open auxiliary contact for signaling or interlocking purposes. Terminations use screw terminals on both the main contacts and the auxiliary contact, enabling secure wiring in DIN rail panel installations. As part of the Siemens SIRIUS 3RT family, the 3RT2017-1AB01 employs the compact S00 frame, which supports compatibility with additional 3RT accessories and auxiliary contact blocks to tailor control schemes. Typical applications include small to mid-size three-phase motor drives, pumps, conveyors, and fans in industrial automation, where a 400 V supply is switched by a 24 V control signal with reliable AC-3e switching and straightforward wiring.
