Rated 250 W at 400 V (50/60 Hz) in AC-3 duty, it handles reversing applications like conveyor drives, gate actuators, and pump direction changes where the load inertia is moderate. ## Size S0 envelope and DIN rail fit Size S0 load feeder with snap-on fastening to 35 mm standard rail — no screws or brackets needed for the mounting base, though the reversing assembly adds height at 265 mm. Depth is 120 mm, width 90 mm — the reversing interlock and busbar adapter (supplied as 3RA2922-1AA00) sit within this footprint, so the panel cut-out and gland plate clearance are the same as a single-direction S0 starter. Clearance requirements: 30 mm upwards, 10 mm forwards and downwards, 9 mm at the side, 0 mm backwards — the back face sits flush against the mounting plate. ## Thermal overload and environmental limits The overload release is thermal bimetallic — it tracks motor heating by sensing current through a bimetal strip, not electronic, so it's immune to harmonics and works without auxiliary power. Operating temperature range is -20 to +60 °C; storage range -50 to +80 °C; transport range -55 to +80 °C — suitable for unheated warehouses and truck transport in most climates. Degree of pollution 3 means the starter is rated for conductive pollution environments typical of industrial control panels — no additional conformal coating needed for normal factory air. The supplied contactor is 3RT2023-1AK60, the link module is 3RA2921-1AA00, and the busbar adapter is 3RA2922-1AA00 — all current catalog items, so replacement modules are available if a single component fails in the field.","metaTitle":"Siemens 3RA2225-0JB23-0AK6 SIRIUS Reversing Motor Starter","metaDescription":"Siemens 3RA2225-0JB23-0AK6 SIRIUS reversing motor starter, size S0, 250 W at 400 V, Class 10, snap-on DIN rail.
