45 mm wide, S0 frame, Class 10 trip
The 3RA2120-1DA23-0AP6: This SIRIUS 3RA2 non-fused motor starter is a direct starter in the S0 size, 45 mm wide on the DIN rail — it takes up two standard 22.5 mm module slots in a control panel, so plan the rail accordingly.
Power ratings across the voltage range
At 400 V AC-3, the motor starter is rated for 1 100 W (1.5 hp) with a full-load current of 2.8 A; at 460/480 V it delivers 1.5 hp, and at 575/600 V it delivers 2 hp at 3.16 A — the current rating climbs with voltage as the motor draws less per horsepower. The contactor inside is a 3RT2023-1AP60, and the supplied link module is 3RA2921-1AA00 — these are the factory-matched pair, so the thermal and magnetic coordination between the contactor and overload is already set out of the box.
