Siemens 3RT2018-1AP01 Three Phase AC Contactor

Siemens 3RT2018-1AP01 is a compact, 3-pole power contactor from the 3RT series designed for AC-3 and AC-3e motor switching. It handles up to 16 A and up to 7.5 kW when operated at 400 V, with a 230 V AC coil rated for 50/60 Hz, and it uses screw-terminal connections for secure wiring in panel installations. The device is built in the small S00 frame size and includes one normally open auxiliary contact for signaling or interlocking functions. This combination makes it well suited for energizing and de-energizing three-phase motors, pumps, and other industrial loads within control cabinets, aligning with Siemens automation ecosystems and offering a reliable, replaceable component in standard 3RT footprints.
