It ships with the contactor (3RT2023-1BB40), link module (3RA2921-1BA00), and busbar adapter (3RA2922-1AA00) already integrated, so the panel builder gets a tested, pre-wired reversing pair. ## DIN rail footprint and clearances Snap-on mounting on 35 mm DIN rail, vertical orientation only. The envelope is 90 mm wide × 265 mm tall × 130 mm deep — size S0 load feeder format. Keep 30 mm clearance above, 10 mm below, 10 mm in front, and 9 mm at the sides for airflow and wiring access. ## Rated for motor duty across common voltages AC-3 switching duty rated up to 690 V maximum. At 400 V it handles 1 100 W (roughly 1.5 hp); at 480 V the full-load current is 2.8 A; at 500 V it covers 1 500 W. Horsepower ratings span from 0.1 hp at 110/120 V up to 2 hp at 575/600 V — a right-sized spec for small conveyors, pumps, and fans. Coil voltage is 24 V, operating frequency 50/60 Hz. The pollution degree is 3 (conductive or dry non-conductive pollution that becomes conductive due to condensation), so the starter is suited for industrial enclosures where dust and humidity are present.","metaTitle":"Siemens 3RA2220-1DB23-0BB4 SIRIUS reversing starter","metaDescription":"Siemens 3RA2220-1DB23-0BB4 SIRIUS non-fused reversing motor starter, CLASS 10 thermal overload, snap-on 35 mm DIN rail.
