SIRIUS S00 direct starter — what ships in the box
The 3RA2110-1KE17-1AP0: This is a Siemens SIRIUS direct (on-line) starter, size S00, meaning it combines a contactor and overload relay in one assembly for controlling a single motor — no separate wiring between the two devices. The supplied contactor is a 3RT2017-2AP01 and the link module is a 3RA2911-2AA00, so the starter arrives as a matched pair ready to snap onto the rail.
Mounting and clearances — 45 mm wide, needs breathing room
The starter measures 45 mm wide by 198 mm tall by 97 mm deep and mounts vertically on a 35 mm DIN rail with a screw-and-snap-on fastening method. For heat dissipation, Siemens specifies minimum clearances: 50 mm above, 20 mm below, 20 mm to the side, and 20 mm in front — zero clearance behind the unit.
Trip Class 10 — what it means for motor protection
This is the standard class for general-purpose motor starting — it allows the inrush current to pass during acceleration but protects the motor windings if the rotor stalls or the load jams. For high-inertia loads that need a longer acceleration ramp, a Class 20 or 30 starter would be needed; this one is sized for normal-duty conveyors, pumps, and fans.
Motor ratings across common voltages
At 400 V the rating is 5.5 kW, and at 230 V it covers 2 hp.
