It comes supplied with a 3RT2015-1BB41 contactor, a 3RA1921-1DA00 link module, and an 8US1251-5DS10 busbar adapter — so the panel builder gets a matched set, not a bag of loose parts. The coil pulls 24 V DC (rated value), and the thermal bimetallic overload release is set to CLASS 10 trip curve, sized for motor protection on standard induction motors up to the S00 frame. ## Motor power coverage across common line voltages At 400 V AC-3 duty this starter is rated for 1 500 W (2 hp); at 460/480 V it handles 2 hp; at 575/600 V it reaches 3 hp — so a single BOM line covers 400 V to 600 V three-phase motors without a variant swap. ## Panel fit and mounting constraints Width is 45 mm, depth 155.1 mm, height 200 mm — fits a standard S00 footprint on a 60 mm busbar system; snaps on without tools. Mounting position must be vertical; clearance above the unit is 20 mm, below 10 mm, and 9 mm at the sides — no space needed forward or backward. Operating temperature range is -20 to +60 °C, storage -50 to +80 °C, transport -55 to +80 °C — fine for most panel environments, but watch the upper end near a hot drive or transformer.","metaTitle":"Siemens 3RA2115-1ED15-1BB4 SIRIUS Non-Fused Motor Starter","metaDescription":"Siemens 3RA2115-1ED15-1BB4 SIRIUS non-fused motor starter, size S00, 24 V coil, CLASS 10 trip, AC-3 rated to 690 V.
