It ships with two 3RT2026-2AC20 contactors already mounted and wired on a common base plate. ## Motor ratings that govern the selection In AC-3 duty (starting and running motors), the assembly delivers 11 kW at 400 V, 21 A at 480 V, and 22 A at 600 V. Two instantaneous auxiliary contacts are built in — enough for a basic seal-in and status feedback to a PLC without adding a separate auxiliary block. ## Mounting, wiring, and panel fit The assembly mounts on 35 mm standard DIN rail via the screw-and-snap-on method. The magnet coil also terminates on spring-type terminals — no screwdriver needed for the control wiring. Envelope dimensions are 114 mm high, 90 mm wide, and 97 mm deep. Clearance requirements: 6 mm upward, downward, and to the side; 0 mm backward (flush against the rail); 6 mm forward. These are the minimum gaps for ventilation and arc clearance — tighter layouts risk thermal buildup. ## Environmental and mechanical endurance Shock resistance is 13.5 g / 5 ms and 8.3 g / 10 ms on AC, 15 g / 5 ms and 10 g / 10 ms on DC.","metaTitle":"Siemens 3RA2326-8XB30-2AC2 SIRIUS Reversing Contactor","metaDescription":"Siemens SIRIUS reversing contactor assembly 3RA2326-8XB30-2AC2, 11 kW at 400 V AC-3.
