Star-delta contactor assembly, S00 frame
The Siemens 3RA2417-8XF31-1AB0 is a pre-assembled star-delta (wye-delta) contactor assembly from the SIRIUS family, built on the S00 frame size. It ships with three contactors: two 3RT2018-1AB01 and one 3RT2016-1AB01, plus the RS assembly kit 3RA2913-2BB1.
Mounting and wiring flexibility
All power, auxiliary, and control connections use screw-type terminals. AWG equivalents are 2x (20…16) and 2x (18…14). Overall dimensions are 135 mm wide, 145 mm deep, and 68 mm high — the depth is the key panel clearance figure.
Coil and environmental ratings
The assembly withstands shock at 11.4 g / 5 ms and 7.3 g / 10 ms in both AC and DC directions. Clearance around the unit: 6 mm upwards, forwards, downwards, and to the side; 0 mm backwards — meaning it can sit flush against a back panel or enclosure wall.
