The supplied contactor is a 3RT2026-1BB40, and the link module is 3RA2921-1BA00 — the assembly is factory-matched for coordination. ## Panel fit and mounting Dimensions are 90 mm wide, 130 mm deep, and 265 mm tall — the S0 frame size fits standard 35 mm DIN rail via the included adapter for screw or snap-on mounting. Mounting position is vertical only; clearance requirements are 50 mm upward, 32 mm forward, 10 mm downward, and 10 mm at the side for airflow and wiring access. The main circuit uses screw-type terminals, so no special crimp tooling is needed for field wiring. The supplied RH assembly kit (3RA2923-1BB1) provides the reversing interlock hardware. ## Lifecycle and sourcing Operating temperature range is -20 to +60 °C with temperature compensation active across that band. Storage and transport limits are -50 to +80 °C. The substance prohibitance date of 10/01/2009 indicates RoHS compliance per Siemens documentation.","metaTitle":"Siemens 3RA2220-4AB26-0BB4 SIRIUS Reversing Starter","metaDescription":"Siemens 3RA2220-4AB26-0BB4 SIRIUS reversing starter, 7.5 kW at 400 V AC-3, Class 10, S0 size.
