The unit ships with the contactor (3RT2023-1AK60), link module (3RA2921-1AA00), busbar adapter (3RA2922-1AA00), and RH assembly kit (3RA2923-1BB1) already integrated — you wire the main and control circuits, not assemble sub-components. ## Class 10 trip and the thermal-magnetic pair The short-circuit trip is magnetic (instantaneous), so the starter clears a bolted fault without waiting for the bimetal to heat up — the two protection functions work in parallel, not series. Rated power at 400 V is 180 W; at 500 V it's also 180 W, and at 690 V it reaches 250 W — the power rating climbs with voltage because the contactor's breaking capacity improves as the current drops for the same power. ## Panel fit — clearances and DIN rail space The starter measures 90 mm wide, 120 mm deep, and 265 mm tall — it occupies three 18 mm DIN-rail module positions plus some vertical headroom for the reversing contactor stack. Clearance requirements: 30 mm upward, 10 mm forward, 10 mm downward, 9 mm to the side, and 0 mm backward — meaning it can sit flush against the back panel, which saves depth in shallow enclosures. Mounting position is vertical only; the snap-on fastening on 35 mm standard rail means no tools for installation, but the vertical orientation is mandatory for the thermal overload to sense correctly. ## Coil voltage and operating conditions The control coil accepts 88–121 V at 50 Hz and 96–132 V at 60 Hz — a 110 V control transformer with ±10% tolerance covers both ranges; the wider 60 Hz band accounts for the higher impedance at 60 Hz. Ambient operating range is -20 to +60 °C; storage range is -50 to +80 °C; transport range is -55 to +80 °C — the wider transport range allows cold-weather shipping without pre-conditioning. ## Wiring — main contact terminals Main contacts accept stranded wire from 1 to 10 mm², or two parallel conductors of 2.5 to 6 mm² each — useful for paralleling feeds in high-current reversing applications. AWG equivalents: 2x (16–12) or 2x (14–8) — the dual-conductor capability is common on Siemens S0 starters for looping power through the top terminals. ## Lifecycle and sourcing — active, quoted to order The substance prohibitance date of 03/01/2017 indicates RoHS/REACH compliance documentation is on file — the starter meets EU substance restrictions as of that date.","metaTitle":"Siemens 3RA2225-0GB23-0AK6 SIRIUS Reversing Starter, S0","metaDescription":"Siemens 3RA2225-0GB23-0AK6 SIRIUS non-fused reversing motor starter, size S0, Class 10 thermal overload, 180 W at 400 V.
