Main contacts are 3 NO rated at 20 A; the auxiliary contact block carries 1 NC and 1 NO, identified as switching element 11. Dimensions are 45 mm wide by 110 mm deep by 110 mm tall, so it occupies a standard 45 mm module width on the rail. Both main and auxiliary circuits use screw-type terminals, so no special tooling is needed for field wiring. This part is marked as a phased-out product — the official Siemens successor is the SIRIUS 3RT2 series, specifically order code 3RT2617-1AK63. For a BOM line that still calls out 3RT1617-1AK63, the replacement is a form-fit-function drop-in: same 45 mm width, same AC coil voltage, same AC-6 kVAr rating, and same auxiliary contact configuration. The 3RT2 series uses the same DIN-rail footprint and terminal layout, so no panel rework is required. ## Environmental and protection class IP20 rated on the front and at the terminals, so it is suitable for installation inside a locked enclosure where personnel cannot contact live parts — standard for panel-mounted contactors.","metaTitle":"Siemens 3RT1617-1AK63 Capacitor Contactor, AC-6 12.5 kVAr, 1","metaDescription":"Siemens SIRIUS 3RT1617-1AK63 capacitor contactor, AC-6 duty, 12.5 kVAr at 400 V, 110 V AC coil.
