The 24 V control coil keeps the control circuit at safe extra-low voltage, common in PLC-controlled panels where 24 VDC is the standard logic rail. ## DIN rail mounting and panel footprint Snap-on fastening on 35 mm standard rail, vertical mounting position only — the 90 mm width and 130 mm depth fit a size S0 feeder slot, with 30 mm upward clearance and 10 mm forward clearance for wiring and heat dissipation. The supplied link module (3RA2921-1BA00) and busbar adapter (3RA2922-1AA00) are pre-configured for this reversing configuration, reducing panel wiring time. ## Supplied contactor and wiring range Includes the 3RT2023-1BB40 contactor as the switching element, rated for electromechanical AC-3 duty. Main contact wiring accepts 1–10 mm² stranded or 2×(2.5–6 mm²), with AWG equivalents of 2×(16–12) or 2×(14–8).","metaTitle":"Siemens 3RA2220-1BB23-0BB4 SIRIUS reversing starter","metaDescription":"Siemens SIRIUS 3RA2220-1BB23-0BB4 non-fused reversing motor starter, size S0, CLASS 10 thermal overload, 24 V coil, 50-60 Hz.
