It is built around the supplied 3RT2023-1AK60 contactor and a 3RA2921-1AA00 link module, with the circuit-breaker sized S00 and the load feeder sized S0. ## Trip Class 10 and the motor protection curve At 460/480 V the starter is rated 2 hp; at 575/600 V it handles 3 hp. ## Snap-on busbar mounting and panel clearances Fastening method is snap-on onto 60 mm busbar systems — no DIN rail adapter needed, the starter clips directly to the busbar support. Mounting position must be vertical. The envelope is 260 mm high × 90 mm wide × 155 mm deep. Clearance requirements: 30 mm upwards, 10 mm forwards, 10 mm downwards, 9 mm at the side, and zero backwards — so the back can sit flush against the panel backplate.","metaTitle":"Siemens 3RA2220-1ED23-0AK6 SIRIUS Reversing Motor Starter","metaDescription":"Siemens 3RA2220-1ED23-0AK6 SIRIUS reversing motor starter, size S0, Trip Class 10.
