Star-delta contactor assembly — what's inside and where it fits
The 3RA2417-8XF31-2AP0-ZX95: This is a Siemens SIRIUS contactor assembly purpose-built for star-delta (wye-delta) motor starting — it ships as a pre-configured set with three contactors: two 3RT2018-2AP01 units and one 3RT2016-2AP01, plus the RS assembly kit 3RA2913-2BB2.
Mounting and wiring — what the DIN rail and terminals tell you
Mounts on 35 mm standard rail with screw or snap-on fastening. The magnet coil also terminates on spring-type terminals — no screw torque to check, just strip and push. Clearance around the assembly: 6 mm upwards, forwards, downwards, and to the side; 0 mm backwards (flush to the rail). That 6 mm gap is the minimum for airflow and tool access — don't crowd it.
Environmental and compliance — operating range and substance restrictions
The vibration endurance is 11.4 g / 5 ms and 7.3 g / 10 ms on both AC and DC — tested to the same spec regardless of supply type. RoHS compliance date is 10/01/2009 — the assembly meets the EU substance restrictions from that date forward. No bus communication module or auxiliary switch is included as standard.
Lifecycle and sourcing — current production, quoted to order
