Its AC coil, screw-type terminals, and 45 mm width make it a direct fit for standard 35 mm DIN rail (DIN EN 50022) enclosures where space is tight — the S00 frame keeps the footprint compact at 125 mm tall by 120 mm deep. Rated for capacitor switching at 230 V AC (6 A), 400 V AC (3 A), and 690 V AC (1 A), it handles the inrush currents typical of discharged capacitor banks without welding contacts — the arcing time of 10 to 15 ms and AC switching time of 4 to 15 ms are tuned for that duty. The headline numbers — 6 A at 230 V AC, 3 A at 400 V AC, 1 A at 690 V AC — are the capacitive load ratings, not the general-purpose AC-1 or AC-3 motor ratings you see on standard contactors. Capacitor contactors must handle higher peak inrush (often 20–30× rated current for a few milliseconds) without contact bounce or welding. The SIRIUS design addresses this with dedicated damping resistors or pre-charge circuits integrated into the contactor block; the 3RT2617-1AK63 is rated for a maximum of 180 switching cycles per hour across the entire voltage range from 230 V to 690 V, which matches typical PFC step-switching intervals. Screw-type terminals accept solid or stranded conductors: 2× (0.5 to 1.5 mm²), 2× (0.75 to 2.5 mm²), or 2× 4 mm². At 40 °C ambient, the terminal rating allows 1× 4 mm² or 2× 2.5 mm²; at 60 °C, 2× 4 mm² is permitted. ## Environmental limits","metaTitle":"Siemens 3RT2617-1AK63 SIRIUS Capacitor Contactor, Size S00,","metaDescription":"Siemens 3RT2617-1AK63 SIRIUS capacitor contactor, size S00, 45 mm wide, screw terminals, AC coil.

The 3RT2617-1AK63 is specifically designed for capacitor switching with higher inrush handling and dedicated damping — dropping a standard contactor into a PFC panel risks contact welding. Stick with the capacitor-rated order code for that application."},{"question":"Will 3RT2617-1AK63 drop into a panel specified around 3RT1017-1AK61 without rewiring?","answer":"Both are size S00 contactors on the same 45 mm DIN-rail footprint, so the mechanical fit and terminal layout are identical. The 3RT2617-1AK63 uses screw terminals with the same wire ranges (0.5 to 4 mm² solid/stranded), so no rewiring is needed for the power and control connections. The difference is internal: the capacitor contactor has additional inrush damping components that the standard motor contactor lacks."},{"question":"What compliance documentation does Siemens provide for 3RT2617-1AK63?","answer":"As a SIRIUS product, the 3RT2617-1AK63 is covered by Siemens' standard declarations of conformity (CE, UKCA) and material compliance declarations (RoHS, REACH). UL and CSA certifications are typical for the SIRIUS contactor family, though the specific file numbers are not listed in this evidence set.
