It ships as a pre-assembled unit with a 3RT2027-1AP60 contactor, a link module (3RA2921-1AA00), and a busbar adapter (3RA2922-1AA00) — everything needed to reverse a motor in one package, no separate interlock wiring. ## Rated for 27 A at 480/600 V, covers 5–25 hp range At 480 V AC it carries 27 A (20 hp); at 600 V it also carries 27 A (25 hp). Lower-voltage ratings: 10 hp at 200/208 V and at 220/230 V, 15 kW at 400 V, 18.5 kW at 500 V. The AC-3 switching maximum is 690 V. Coil voltage range is 176–242 V at 50 Hz and 192–264 V at 60 Hz — covers 208–240 V nominal supplies with margin. ## Snap-on DIN rail, vertical mount, 120 mm deep Overall dimensions: 120 mm deep, 90 mm wide, 265 mm tall. Clearance requirements: 30 mm upward, 10 mm forward, 10 mm downward, 9 mm at the side, 0 mm backward — so it can sit flush against a back panel. Operating temperature range -20 to +60 °C; storage -50 to +80 °C; transport -55 to +80 °C. Pollution degree 3 (conductive pollution or dry non-conductive that becomes conductive due to condensation — typical for control panels in industrial environments).","metaTitle":"Siemens 3RA2220-4EB27-0AP6 Motor Starter, Reversing, S0","metaDescription":"Siemens SIRIUS 3RA2220-4EB27-0AP6 non-fused reversing motor starter, CLASS 10, 27 A at 480/600 V, snap-on DIN rail.
