What this reversing starter delivers
The 3RA2220-1KB24-0AK6: It ships with the contactor 3RT2024-1AK60 and the link module 3RA2921-1AA00 already integrated, so the reversing interlock and mechanical linkage are factory-set.
Panel fit and mounting
Mounts on a 35 mm DIN rail via the supplied adapter, or directly with screws — the fastening method is listed as 'on adapter for screw and snap-on mounting on 35 mm standard mounting rail'. Dimensions are 90 mm wide, 120 mm deep, 265 mm tall — the depth is the critical dimension for enclosure depth clearance; the width fits a standard S0 feeder slot. Clearance requirements: 50 mm upwards, 32 mm forwards, 10 mm at the sides and downwards, 0 mm backwards — plan the enclosure layout accordingly for ventilation and wiring access. Rated for vertical mounting position only — horizontal mounting would alter the thermal overload trip curve.
Electrical ratings and duty
At 400 V, the rated motor power is 5.5 kW; at 480 V the rated current is 11 A in AC-3 duty (switching squirrel-cage motors). Control voltage is 88–121 V at 50 Hz and 96–132 V at 60 Hz — a dual-frequency coil that works on common control transformer taps.
Lifecycle and sourcing
The supplied contactor (3RT2024-1AK60) and link module (3RA2921-1AA00) are standard SIRIUS catalog items, so replacement spares are straightforward to source separately if needed.
