The Siemens SIRIUS 3RA2316-8XB30-1AP6 is a factory-assembled reversing contactor assembly in frame size S00. It ships with two 3RT2016-1AP62 contactors mechanically and electrically interlocked, so you get a ready-to-wire reversing starter out of the box — no separate interlock kit to source or install. Rated 4 kW at 400 V AC-3 (7.6 A at 480 V, 9 A at 600 V), it handles reversing motor loads up to 7.5 hp at 575/600 V.
Snap-on mounting onto 35 mm standard DIN rail, with screw terminals for both main and coil circuits. The assembly occupies 90 mm width, 73 mm deep, 68 mm tall. Clearance requirements are minimal — 6 mm upwards, forwards, downwards, and to the side; zero backwards clearance needed. Wire capacity covers solid and stranded conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and 2x 4 mm².
