SIRIUS S00 power contactor — 3RT1017-1AP01-ZW98
The Siemens SIRIUS 3RT1017-1AP01-ZW98 is a size S00 power contactor rated for 10 A in AC-12 duty (resistive loads at 230 V) and 5.5 kW in AC-2 duty at 400 V — the motor-switching rating that governs most panel applications. The AC-4 rating of 8.5 A at 400 V covers reversing or inching duty where contact wear is higher. Screw-type terminals on the main circuit accept 2x (0.5…1.5 mm²) solid or 2x (0.75…2.5 mm²) stranded, with a maximum of 2x (0.75…4 mm²) — no ferrule crimping needed for standard panel wiring. Mounting is screw or snap-on onto 35 mm DIN rail per DIN EN 50022. The 45 mm width and 72 mm depth fit standard enclosure grids; side-by-side mounting is permitted with 6 mm clearance to adjacent devices. Front and terminal protection is IP20 — suitable for enclosed panels, not washdown zones.
Integration notes
Operating temperature range is -25 to +60 °C, with a maximum altitude of 2000 m. Pollution degree 3 means the contactor tolerates conductive dust and occasional condensation — typical for industrial control panels not in clean-room environments. For Type 2 coordination (no-weld), use a gL/gG fuse rated 20 A; for Type 1 coordination, 35 A. Mechanical life is 30,000,000 operations — the auxiliary contact block and coil are the wear items that drive replacement intervals.
