Rated 6.3 A in AC-3 at 400 V, meaning it handles a 2.2 kW motor at that voltage without the contactor welding shut on a stalled start. That's standard for general-purpose motor starting; you don't get the longer Class 20 window for high-inertia loads. ## What's in the box and how it mounts The starter ships with the 3RT2024-1BB40 contactor and the 3RA2921-1BA00 link module already wired and interlocked. The circuit-breaker is size S00, so the whole assembly fits a 90 mm wide footprint on 35 mm DIN rail — snap-on or screw-mount via the adapter. Depth is 130 mm, height 265 mm. Mounting position is vertical only. Clearances: 50 mm above, 32 mm in front, 10 mm at the sides and below — no clearance needed behind the DIN rail. That's tight enough for a shallow enclosure but the top clearance is non-negotiable for the arc chamber. ## Coil voltage and operating range Coil is 24 V DC, rated 24... 24 V — no tolerance band wider than that. If your control transformer feeds 24 V nominal, it'll pull in fine; don't expect it to hold in at 20 V. Operating temperature is -20 to +60 °C, storage and transport -50 to +80 °C. The temperature compensation is active across the same -20 to +60 °C range, so the overload trip curve stays accurate in a hot panel. ## Sourcing — active, quoted to order The 3RA2220-1GB24-0BB4 is a standard catalog item in the SIRIUS line. No direct functional second-source from other manufacturers — the 6ES7517-3FP00-0AB0 and 6ES7214-1BG40-0XB0 are Siemens PLC CPUs, not motor starters, so they won't drop into this panel position without a complete rewire.","metaTitle":"Siemens 3RA2220-1GB24-0BB4 SIRIUS Reversing Starter","metaDescription":"Siemens 3RA2220-1GB24-0BB4 SIRIUS reversing starter, 6.3 A at 400 V AC-3, Class 10 trip, size S0.
