What ships in the carton — a complete kit
The 3RA2115-1AD15-1AK6 is a Siemens SIRIUS non-fused motor starter, a direct starter in size S00 that ships as a factory-assembled unit with the contactor, overload relay, link module, and busbar adapter already integrated. The supplied contactor is the 3RT2015-1AK61, the link module is the 3RA1921-1DA00, and the busbar adapter is the 8US1251-5DS10 — no separate ordering of subcomponents needed for the basic assembly.
Motor power coverage and voltage flexibility
At 400 V rated value the starter handles 550 W; at 690 V rated value it handles 1,100 W. At 460/480 V it is rated 0.75 hp, and at 575/600 V also 0.75 hp. The main contact rating at 480 V is 1.6 A, and at 600 V it is 1.3 A — the current decreases as voltage increases due to the AC-3 switching duty limits. Rated insulation voltage is 690 V, with AC-3 switching maximum also at 690 V — the contactor and overload are designed for 690 V line-to-line systems common in 400/690 V industrial networks.
Mounting on busbar — panel integration notes
This starter is designed for snapping onto 60 mm busbar systems — the integral busbar adapter (8US1251-5DS10) clips directly onto standard 60 mm center-distance busbars, eliminating separate DIN-rail mounting hardware. Mounting position is vertical only. Dimensions: 45 mm wide, 200 mm tall, 155.1 mm deep — the 45 mm width matches the S00 footprint, fitting two starters per standard 100 mm busbar section. Clearance requirements: 20 mm upwards, 10 mm downwards, 9 mm at the side, 0 mm forwards and backwards — the zero forward/backward clearance means the starter can be mounted flush against a panel backplate or enclosure wall.
