Factory-assembled wye-delta set — what you get
The 3RA2423-8XF32-1AG2: This is a complete star-delta contactor assembly from the Siemens SIRIUS family, not a loose collection of parts. It ships with three 3RT2024-1AG20 contactors and the 3RA2923-2BB1 RS assembly kit installed — you mount it as one unit. Rated motor power is 11 kW at 400 V, 50/60 Hz, stepping up to 15.6 kW at 500 V and 19 kW at 690 V. The coil is 110 V at 50 Hz or 60 Hz. Contactor frame size is S0 — the standard footprint for this power band. All three contactors are identical, which simplifies spares stocking.
Mounting and wiring — panel fit
Mounts on 35 mm DIN rail via screw or snap-on fastening. The assembly is 135 mm wide, 101 mm tall, and 171 mm deep — measure your backpanel clearance before committing. Clearance around the unit: 6 mm upwards, forwards, downwards, and sideways; 0 mm backwards (the back sits flat on the rail). AWG equivalents: 2x (16...12) or 2x (14...8). Coil and auxiliary/control terminals also use screw-type connections — no spring-cage option on this variant.
Environmental and mechanical limits
Shock resistance: 11.8g at 5 ms (AC) and 15g at 5 ms (DC). Mechanical life of the contactor is rated at 10,000,000 operating cycles typical. No auxiliary switch or bus communication module is included or available as a factory extension on this order code. RoHS compliance date reference is 10/01/2009 — the assembly meets the EU RoHS directive effective from that date.
Because it's a factory-integrated assembly of standard SIRIUS components, the individual contactors (3RT2024-1AG20) and the RS kit (3RA2923-2BB1) are also available separately for field service or replacement.
