Star-delta assembly — what ships in the box
The 3RA2416-8XF31-1AB0 is a Siemens SIRIUS pre-assembled contactor combination for star-delta (wye-delta) motor starting. It ships with three contactors: two 3RT2017-1AB01 units for the line and star legs, and one 3RT2015-1AB01 for the delta leg. Coil voltage is 24 V at 50/60 Hz, drawing 0.25 A at both frequencies — the magnet coil is screw-terminated, same as the main and auxiliary circuits.
Mounting and panel fit
The S00 frame size keeps the footprint compact: 68 mm high, 135 mm wide, 145 mm deep — the depth is the dimension that matters for shallow enclosures. Clearance around the unit: 6 mm upwards, forwards, downwards, and to the side; 0 mm backwards — it can sit flush against the back panel. Wire termination uses screw-type terminals throughout. AWG equivalents are 2x (20...16) and 2x (18...14) for the main contacts.
Environmental and mechanical endurance
The assembly handles shock loads of 10.5g at 5 ms and 6.6g at 10 ms in both AC and DC axes — relevant for installations on vibrating machinery or in mobile equipment. Mechanical life of the contactor is rated at 10,000,000 operating cycles typical — this is the mechanical endurance of the S00 frame, not the electrical life under load, which will be lower depending on the switching current. The assembly includes the supplied RS assembly kit 3RA2913-2BB1. No auxiliary switch or bus communication module is fitted as standard — the product extension auxiliary switch and bus communication function are both listed as 'No'.
Sourcing and compliance
Substance prohibitance date is 10/01/2009 — the assembly complies with RoHS and REACH requirements as of that date. No UL, CSA, or IEC certification marks are listed in the spec record; confirm site-specific approval needs with the full datasheet.
