S00 direct starter for busbar mounting
The 3RA2115-1HD16-1AP6: This is a SIRIUS 3RA2 non-fused motor starter in size S00, configured as a direct starter with a thermal bimetallic overload relay (CLASS 10 trip class). It ships with the 3RT2016-1AP61 contactor and the 3RA1921-1DA00 link module pre-assembled — the BOM line is a single order code, not three separate components. Rated for snapping onto 60 mm busbar systems in a vertical mounting position. The 45 mm width and 155.1 mm depth fit standard S00 panel layouts; clearance requirements are 20 mm upwards, 10 mm downwards, and 9 mm at the side.
Motor power coverage across voltage bands
At 480 V the current rating is 7.6 A; at 600 V it is 6.33 A. The insulation voltage is rated 690 V, matching the AC-3 maximum. Horsepower equivalents span 1 hp at 230 V up to 5 hp at 460/480 V and 575/600 V, covering common North American motor frames in the S00 footprint.
The 3RA2 series is Siemens' standard S00 motor starter platform, so supply continuity is consistent with the broader SIRIUS portfolio. Operating temperature range is -20 to +60 °C, with storage from -50 to +80 °C and transport limits of -55 to +80 °C. Pollution degree 3, suitable for industrial control panels where conductive dust or humidity is present.
