Reversing contactor assembly — SIRIUS S0 frame, 11 kW at 400 V
The 3RA2326-8XE30-2BB4: It ships with two supplied contactors: 3RT2026-2BB40-0CC0 and 3RT2026-2BB40, plus the reversing hardware kit 3RA2923-2AA2 — a complete drop-in reversing starter on a single DIN-rail footprint.
Motor ratings across common line voltages
In AC-4 duty (reversing or inching) at 400 V, the rated power is 7.5 kW — a derating of about 32 % from the AC-3 figure, reflecting the higher switching stress on the contacts during plugging or jogging.
Mounting and integration — DIN rail with rotation flexibility
The assembly dimensions are 90 mm wide, 114 mm high, and 107 mm deep — the S0 frame size fits standard panel cutouts and leaves 6 mm clearance above, below, and to the sides, with zero clearance required at the rear.
Termination and environmental limits
The 24 VDC coil is terminated with spring-type terminals, and the assembly is rated for operation from -25 °C to +60 °C, with storage from -55 °C to +80 °C.
