It comes with three 3RT2024-1AL20 contactors and a mechanical interlock RS assembly kit 3RA2923-2BB1, all pre-mounted on a common base plate. This is a bolt-on solution for reducing inrush current on three-phase induction motors during start-up, switching the windings from star to delta once the motor reaches speed. Rated for AC-3 duty up to 690 V, the assembly delivers 11 kW at 400 V, 15.6 kW at 500 V, and 19 kW at 690 V. The AC-3 rating means it's designed for starting squirrel-cage motors and switching them off while running — the standard duty for contactors in motor control centers and panel builds. Size S0 footprint — 101 mm high, 135 mm wide, 171 mm deep — fits standard panel layouts. Maintain the specified clearances: 6 mm upwards, forwards, downwards, and to the side; 0 mm backwards. Main circuit and control wiring terminate at screw-type terminals. Solid conductors: 2x (1... 2.5 mm²) and 2x (2.5... 10 mm²). Stranded: 2x (0.5... 1.5 mm²) and 2x (0.75... 2.5 mm²). The magnet coil also uses screw terminals.","metaTitle":"Siemens 3RA2423-8XF32-1AL2 SIRIUS Star-Delta Contactor","metaDescription":"Siemens SIRIUS 3RA2423-8XF32-1AL2 star-delta contactor assembly, 11 kW at 400 V AC-3.
