Product details

Power Contactor for Motor Switching

The Siemens 3RT2018-1AK61-Z W97 is a SIRIUS series power contactor rated for AC-3e/AC-3 duty at 16 A, handling motor loads up to 7.5 kW at 400 V. The 3-pole design with a 110 V AC 50 Hz / 120 V 60 Hz coil makes it a direct fit for standard European and North American control voltages in panel builds. The size S00 frame keeps the footprint compact for DIN-rail mounting in crowded enclosures.

The AC-3e rating at 16 A means this contactor is sized for switching three-phase induction motors under full load — the 7.5 kW at 400 V figure is the motor output it can handle, not the contactor's thermal current. The 1 NO auxiliary contact provides a feedback signal for the PLC or status lamp without needing a separate block. Screw terminals simplify wiring with standard ferrule or ring lugs, and the multi-unit packaging (40 units per pack) suits panel builders ordering in volume.
