Trip Class 10 means it protects standard squirrel-cage motors during start-up without nuisance tripping on normal acceleration, and the 690 V AC-3 maximum covers 400 V, 480 V, and 575 V line voltages common in North American and European panels. ## What drops into the panel – dimensions and mounting At 120 mm deep, 90 mm wide, and 265 mm tall, this reversing starter fits the S0 footprint that Siemens has used across the SIRIUS contactor and feeder range for years – if you already have S0 hardware in the panel, the cut-out and busbar spacing stay the same. ## Active production – no lifecycle surprise The supplied contactor (3RT2024-1AP00) and link module (3RA2921-1AA00) are also current catalog items, meaning replacement spares and expansion modules stay available for the life of the installation. ## Clearance and integration into a populated panel Operating temperature range is -20 to +60 °C, with storage and transport range from -50 to +80 °C – the wider storage band matters if the starter sits on a shelf before commissioning in an unconditioned warehouse.","metaTitle":"Siemens 3RA2220-1KB24-0AP0 SIRIUS Reversing Starter, Size S0","metaDescription":"Siemens 3RA2220-1KB24-0AP0 SIRIUS reversing starter, Size S0, Trip Class 10, 690 V AC-3 max, 120 mm depth, DIN rail mount.
