S0 reversing starter, snap-on busbar mount
The 3RA2225-1HD24-0AK6 is a SIRIUS non-fused reversing motor starter in size S0 — it combines a reversing contactor pair and overload relay in one unit, designed for snapping onto 60 mm busbar systems. The supplied contactor is a 3RT2024-1AK60, and the link module is 3RA2921-1AA00 — the assembly arrives as a factory-matched reversing set.
CLASS 10 trip and motor power across voltages
Current draw is 7.92 A at 480 V and 6.33 A at 600 V. The control coil accepts 88–121 V at 50 Hz and 96–132 V at 60 Hz — a dual-frequency coil that covers 110/120 V control circuits common in North American panels.
Panel fit and clearance envelope
Dimensions are 90 mm wide, 155 mm deep, 260 mm tall. Mounting is vertical only, with required clearances: 30 mm upward, 10 mm forward, 10 mm downward, 9 mm at the side, and 0 mm backward. The S0 footprint and 60 mm busbar snap-on mounting mean it fits standard Siemens panel layouts without additional DIN-rail adapters — the busbar carries the power distribution and the starter clips directly onto it.
