The 3RA2316-8XB34-1CN2 is a Siemens SIRIUS reversing contactor assembly, size S00, meaning it integrates two contactors mechanically interlocked to reverse a three-phase motor without external interlocks. If the application cycles the motor direction while it is still spinning, the AC-4 rating governs the contactor life, not the AC-3 figure.
Mounting and integration — DIN-rail flexibility with screw terminals
Mounts on 35 mm standard DIN rail via screw and snap-on fastening. Dimensions are 90 mm wide, 68 mm high, 130 mm deep — the 90 mm width is the key panel-space figure; allow clearance for the screwdriver swing on the terminals. Main current circuit and magnet coil both use screw-type terminals. That covers the common control-wire sizes in a panel — no ferrule crimping needed for the screw clamp, but the torque spec should be checked against the terminal marking.
RoHS compliance is established with a substance prohibitance date of 07/01/2006, meaning it meets the EU RoHS directive for lead, mercury, cadmium, and the other restricted substances.
