Panel fit and mounting — 45 mm footprint on 60 mm busbar
The 3RA2115-1AD15-1AP6 is a size S00 non-fused motor starter from the SIRIUS 3RA2 family, combining a contactor and thermal overload relay in a direct-starter package. It snaps onto 60 mm busbar systems — the standard spacing in European distribution panels — so the mounting foot is fixed; no DIN-rail adapter needed. At 45 mm wide, 200 mm tall, and 155.1 mm deep, it occupies a single 45 mm busbar slot. Clearance requirements: 20 mm upward, 10 mm downward, 9 mm at the side, and zero forward or backward — meaning adjacent starters or breakers can butt directly against the front and rear faces without derating. Mounting position is vertical only. Ambient operating range is -20 to +60 °C; storage range -50 to +80 °C. The pollution degree 3 rating means it tolerates conductive dust and occasional condensation — typical for unsealed industrial control panels.
Motor ratings — Class 10 trip, 690 V AC-3 ceiling
The supplied contactor is a 3RT2015-1AP61; the link module is 3RA1921-1DA00. Rated insulation voltage is 690 V, matching the AC-3 maximum switching voltage. Power ratings: 550 W at 400 V, 550 W at 500 V, 1.1 kW at 690 V. Current ratings: 1.6 A at 480 V, 1.3 A at 600 V. Horsepower equivalents: 0.1 hp at 230 V, 0.75 hp at 460/480 V and 575/600 V. The control coil is rated for 187–242 V at 50 Hz and 192–264 V at 60 Hz — a wide-range coil that handles both nominal 208/220/230/240 V supplies without a tap change.
Supplied sub-assemblies and wiring
This motor starter ships as a factory-assembled unit containing the 3RT2015-1AP61 contactor, the 3RA1921-1DA00 link module (interconnecting the contactor and overload), and the 8US1251-5DS10 busbar adapter for snapping onto the 60 mm system. The overload release is thermal bimetallic — no electronic settings to configure. The circuit-breaker size is also S00, matching the feeder footprint.
Sourced through independent distribution channels. No minimum order quantity is stated; single-unit and production-lot quotes are both routine for this class of part.
