The 3RA2316-8XB30-1BW4: It ships with two 3RT2016-1BW42 contactors mechanically interlocked, so it handles forward-reverse motor control without extra external wiring.
Motor ratings that fit the panel
At 460/480 V it's rated 5 hp, and at 575/600 V it's rated 7.5 hp. The contactor assembly handles up to 690 V AC-3 maximum, so it covers 400 V through 690 V motor circuits common in North American and European panels. The S00 frame measures 90 mm wide by 68 mm high by 73 mm deep, fitting standard 35 mm DIN rail with screw or snap-on mounting. Clearance around the unit: 6 mm upwards, forwards, downwards, and to the side; 0 mm backwards — meaning it can sit flush against the back panel. The magnet coil and main current circuit both use screw-type terminals, so no special tooling needed for installation.
