Form factor and panel fit — 45 mm wide on 60 mm busbars
The 3RA2110-1KH17-1AP0 is a SIRIUS direct on-line starter in size S00, designed to snap directly onto 60 mm busbar systems — no DIN rail adapter needed. Its width is 45 mm, depth 155 mm, and height 260 mm, so it occupies one standard busbar slot and leaves clearance: 50 mm upwards, 20 mm forwards, and 20 mm at the side for wiring access. Mounting position is vertical only.
Motor protection and trip class — Class 10 for standard starts
For longer acceleration times (high-inertia loads) a Class 20 or 30 unit would be needed, but this starter is matched for typical pump, fan, and compressor duty. The main circuit terminates via spring-loaded terminals, so no screw-torque check is needed on installation — push the stripped conductor in and the cage clamps it. The supplied contactor is a 3RT2017-2AP01 and the link module is 3RA2911-2AA00; these are pre-assembled as a single orderable unit.
Rated power and current — what the spec table shows
At 400 V rated value the spec lists 5,500 kW — this is almost certainly a data-entry anomaly (likely 5.5 kW intended). At 480 V rated value the current is 11 A, and at 600 V rated value it is also 11 A. Horsepower ratings span from 0.5 hp at 110/120 V up to 10 hp at 575/600 V. Ambient operating range is -20 to +60 °C, with storage and transport range of -50 to +80 °C.
