Siemens 3RT2017-2AP02-Z W97 — SIRIUS Size S00 Contactor
The Siemens 3RT2017-2AP02-Z W97 is a 3-pole power contactor from the SIRIUS family, size S00. Its AC-3e/AC-3 rating of 12 A and 5.5 kW at 400 V means it is sized for switching three-phase induction motors up to that power — a 7.5 HP motor on a 400 V line is the practical ceiling. The 230 V AC coil at 50/60 Hz is a standard control voltage across European and many Asian panels, so it drops straight into a 230 V control circuit without a transformer tap. The auxiliary contact block carries 1 NC (normally closed) contact, spring-loaded terminals for fast wiring without screw torque checks, and the S00 frame fits the standard DIN-rail footprint alongside other SIRIUS components. This is a current-production part (lifecycle status active), and it is classified as a made-to-order item (product class C), meaning it is manufactured per order — not a shelf-stocked spare, so plan your procurement lead time accordingly.
