What this SIRIUS direct starter is
The Siemens 3RA2110-0HH15-1AP0 is a SIRIUS direct (on-line) starter in size S00, designed for snapping onto 60 mm busbar systems. It ships as a pre-assembled unit containing the 3RT2015-2AP01 contactor and 3RA2911-2AA00 link module — one order code, one DIN-rail footprint, no separate picking of contactor and overload.
Motor rating and trip class that matter
That 0.8 A AC-3 figure is the motor-switching current — it governs the real-world motor size this starter can handle, not the thermal current. The link module 3RA2911-2AA00 ties the contactor and overload mechanically and electrically; the assembly is tested as a pair, so coordination between the contactor and overload is already validated.
Mounting on 60 mm busbars — panel integration
This starter snaps directly onto 60 mm busbar systems — no DIN rail adapter needed, no extra brackets. The mounting position is vertical only. Clearance requirements: 50 mm upwards, 20 mm forwards, 20 mm at the side, 10 mm downwards, and 0 mm backwards. The 155 mm depth, 45 mm width, and 260 mm height mean it fits into the S00 feeder footprint common across the SIRIUS range.
