No holes in the box — the tech gets the contactor, overload relay, and mechanical interlink in one order code. ## Motor power coverage — 550 W at 400 V, Class 10 trip Rated 550 W at 400 V AC-3 (1.6 A at 480 V, 1.3 A at 600 V), this S00-frame starter covers small motors — pumps, fans, conveyors — up to 0.75 hp at 460/480 V and 575/600 V. ## Snap-on busbar mounting — 60 mm systems Fastens by snapping onto 60 mm busbar systems — no DIN rail required. The vertical mounting position and size S00 footprint (45 mm wide, 155.1 mm deep, 200 mm high) fit standard panel layouts. The supplied busbar adapter 8US1251-5DS10 handles the mechanical and electrical connection to the busbar.","metaTitle":"Siemens 3RA2115-1AD15-1BB4 SIRIUS Motor Starter","metaDescription":"Siemens 3RA2115-1AD15-1BB4 SIRIUS non-fused motor starter, 550 W at 400 V AC-3, Class 10 thermal overload.
