It's built in the compact S00 frame — 45 mm wide, 110 mm deep, 110 mm tall — and snaps onto a standard 35 mm DIN rail per EN 50022. The AC-6 rating means this contactor is specifically designed for switching capacitor banks — the inrush current from a discharged capacitor is much higher than a motor start, and the contactor's arc chambers and contact materials are engineered to handle that repetitive surge without welding. At 12.5 kVAr / 400 V, it's sized for a typical 3-phase power-factor correction bank in a distribution panel. ## Integration Notes The S00 footprint (45 mm wide) leaves room for adjacent devices on the same rail — side-by-side mounting is permitted. The 110 V AC coil draws at 50/60 Hz; verify the control transformer taps match before wiring.","metaTitle":"Siemens 3RT1617-1AF03 Capacitor Contactor, 20 A, 110 V AC, 3","metaDescription":"Siemens SIRIUS 3RT1617-1AF03 capacitor contactor, 20 A rated, 110 V AC 50/60 Hz coil, 3-pole, size S00.
