Envelope dimensions: 265 mm high, 90 mm wide, 120 mm deep — the depth is the critical number when planning a shallow backpanel enclosure, and the 90 mm width matches the standard S0 feeder footprint. Clearance requirements: 50 mm upwards, 32 mm forwards, 10 mm at the sides, 10 mm downwards, and 0 mm backwards — the zero backward clearance means it can sit flush against a backplate or busbar support. ## Electrical ratings and operating range Maximum AC-3 rated voltage is 690 V, and the operating frequency covers 50 to 60 Hz — the coil supply must match the tap: 88–121 V at 50 Hz, 96–132 V at 60 Hz. Ambient operating range is -20 to +60 °C, with storage and transport limits of -50 to +80 °C — the bimetallic overload release compensates over the full operating band. The overload release is thermal bimetallic (ambient-compensated), and the short-circuit trip is magnetic — both housed in the size S0 circuit-breaker frame. ## Lifecycle and sourcing RoHS compliance date is 05/01/2012 — the part meets the EU RoHS directive for substances of concern.","metaTitle":"Siemens 3RA2220-4CB27-0AK6 SIRIUS Reversing Starter","metaDescription":"Siemens 3RA2220-4CB27-0AK6 SIRIUS reversing starter, 11 kW at 400 V AC-3, Class 10, size S0.
