Product details

What ships in the carton — a complete kit

The 3RA2115-1AD15-1BB4: This 3RA2 non-fused motor starter ships as a pre-assembled direct starter: the supplied contactor is 3RT2015-1BB41, the link module is 3RA1921-1DA00, and the busbar adapter is 8US1251-5DS10. 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.
