The 11 kW motor power rating at 400 V matches standard IEC frame sizes for this current class. Size S0 load feeder — the physical frame size determines the busbar spacing and mounting hole pattern. The 155 mm depth, 90 mm width, and 260 mm height fit standard 60 mm busbar centers with 50 mm clearance upward and 32 mm forward. The kit is complete: contactor, circuit-breaker, and link module ship as one orderable unit — no separate sourcing of subcomponents needed. The auxiliary switch extension is supported (product extension auxiliary switch: Yes) if your application requires feedback contacts. Compliance: RoHS substance prohibition date 05/01/2012 — the part meets EU RoHS requirements. Rated surge voltage resistance 6 kV, operating frequency 50/60 Hz, operating temperature range -20 to +60 °C.","metaTitle":"Siemens 3RA2220-4CD27-0AK6 SIRIUS Reversing Starter","metaDescription":"Siemens SIRIUS 3RA2220-4CD27-0AK6 reversing starter, 22 A at 400 V AC-3, Class 10 thermal overload, 11 kW motor rating.
