Star-delta kit — what's in the box and where it fits
The 3RA2423-8XF32-2AC2 is a pre-assembled SIRIUS contactor assembly for star-delta (wye-delta) motor starting. It ships with three 3RT2024-2AC20 contactors and the RS assembly kit 3RA2923-2BB2 — you mount the whole group as one unit, not piecemeal. Rated motor power at 400 V AC-3 is 11 kW, stepping up to 15.6 kW at 500 V and 19 kW at 690 V. The contactor size is S0, which keeps the footprint compact for a 11 kW starter — 135 mm wide, 114 mm high, 171 mm deep.
Mounting and wiring — panel fit and termination
Main current circuit uses spring-loaded terminals; the auxiliary and control circuit also use spring-loaded terminals. No screw torque to check — the spring clamp holds the conductor.
