4 kW reversing contactor assembly — size S00, DIN-rail mount
The Siemens 3RA2316-8XB30-1TP3 is a SIRIUS reversing contactor assembly — a factory-assembled pair of contactors with mechanical interlock, ready to swap motor rotation direction in a single DIN-rail footprint. Size S00 contactor frame keeps the assembly compact at 90 mm wide × 68 mm high × 73 mm deep — fits standard 35 mm DIN rail with screw or snap-on fastening.
Supplied contactors and surge suppressor
The assembly ships with two 3RT2016-1TP02-0RA0 contactors — each rated the same, matched for reversing duty. The built-in varistor surge suppressor clamps coil-induced transients; no external snubber needed. AWG equivalents: 2×(20…16) and 2×(18…14).
Mounting flexibility and environmental limits
Clearance: 6 mm upward, downward, and to the side; 0 mm backward (flush to rail). Operating temperature range -25 to +70 °C; storage -55 to +80 °C. Shock rated 10.5 g / 5 ms and 6.6 g / 10 ms on both AC and DC axes — suitable for machine-mounted panels with moderate vibration.
