It ships with the 3RT2023-1AK60 contactor and 3RA2921-1AA00 link module pre-assembled. The reversing configuration means two contactors interlocked for forward/reverse control of a three-phase motor, all in one 90 mm wide package — a space saver over separate contactors and a mechanical interlock. ## Class 10 trip and motor protection The S0 frame size matches motor FLA up to about 3 A at 480 V (2.8 A) or 3.16 A at 600 V. The horsepower ratings at 110/120 V (0.1 hp) and 200/208 V (0.5 hp) cover low-voltage control transformer feeds. ## Mounting and clearance envelope Mounts vertically on a 60 mm busbar system via snap-on fastening. Clearance required: 30 mm upwards, 10 mm forwards, 10 mm downwards, 9 mm at the side, 0 mm backwards — the back is flush against the busbar. Overall dimensions 260 mm high × 90 mm wide × 155 mm deep. Main contact wire range accepts 1 to 10 mm² stranded, or 2× (2.5 to 6 mm²) for paralleling feeds. The circuit-breaker size is S00 — a separate upstream protective device, not integrated. ## Environmental limits and compliance Operates from -20 to +60 °C; stores from -50 to +80 °C; transports from -55 to +80 °C. Pollution degree 3 (conductive pollution or dry non-conductive pollution that becomes conductive due to condensation). Substance prohibitance date 03/01/2017 aligns with RoHS compliance milestones. The product brand is SIRIUS, design type assignment 2.","metaTitle":"Siemens 3RA2225-1DD23-0AK6 SIRIUS Reversing Starter, S0","metaDescription":"Siemens 3RA2225-1DD23-0AK6 SIRIUS non-fused reversing motor starter, size S0, Class 10 trip, 690 V AC-3.
