It is a direct starter — meaning the motor sees full line voltage at start — and is rated for AC-3 switching duty up to 690 V. This protects standard squirrel-cage motors during a locked-rotor event without nuisance tripping on normal acceleration. The 480 V rating of 11 A is the figure to check against your motor nameplate FLA. ## Panel fit — 45 mm wide, S00 footprint, two mounting options At 45 mm wide and 97.1 mm deep, this starter occupies a single S00-width slot on the DIN rail. The 167.2 mm height leaves clearance for the push-in lug if screw-mounting is preferred over the snap-on rail clip. Mounting position is vertical only, with 20 mm clearance needed above and 10 mm below for wiring and heat dissipation. No clearance is required forwards or backwards, which simplifies panel layout in dense cabinets. The supplied contactor is a 3RT2017-1AK61, and the link module is 3RA1921-1DA00 — these are the subcomponents that carry the switching and overload functions. ## Sourcing — active line, quoted per BOM Sourced through independent distribution channels, quantities are confirmed at RFQ against the BOM line.","metaTitle":"Siemens 3RA2115-1KA17-1AK6 SIRIUS Motor Starter","metaDescription":"Siemens SIRIUS 3RA2115-1KA17-1AK6 non-fused motor starter, size S00, Class 10 thermal overload, 7.5 hp at 480 V.
