It ships as a coordinated assembly: the supplied contactor (3RT2015-1AK61), circuit-breaker (3RV2011-0FA15), link module (3RA1921-1DA00), and busbar adapter (8US1251-5DS10) are all included. That means one order code lands a fully matched feeder — no hunting for separate overload, breaker, or busbar clips. The thermal bimetallic overload release is Trip Class 10, rated for standard motor start duty up to 690 V AC-3 at 50/60 Hz. ## Panel fit and busbar snap-on This starter snaps directly onto 60 mm busbar systems — no extra DIN-rail adapter needed for that mounting method. The vertical mounting position is specified. Dimensions are 200 mm height, 45 mm width, and 155.1 mm depth, with 20 mm clearance required above, 10 mm below, and 9 mm at the side. Forwards and backwards clearance is 0 mm. The Size S00 footprint is compact enough for dense panel layouts where busbar-fed feeders are preferred over point-to-point wiring. The AC-3 rating at 690 V maximum means this starter handles squirrel-cage motor switching — starting, stopping, and occasional inching — up to that voltage. The supplied circuit-breaker provides magnetic short-circuit protection coordinated to the contactor and overload, so a fault downstream clears without welding the main contacts.","metaTitle":"Siemens 3RA2115-0FD15-1AK6 SIRIUS Non-Fused Motor Starter","metaDescription":"Siemens 3RA2115-0FD15-1AK6 SIRIUS non-fused motor starter, Size S00, Class 10, 690 V, 50/60 Hz.
