Active production — what that means for procurement
The lifecycle stage for this 3RA2326-8XB30-1AL2-ZW96 is listed as current, meaning Siemens continues to manufacture it as an active catalogue item. No end-of-life notice or last-time-buy window is in effect.
Motor ratings and switching duty
Rated 11 kW at 400 V (AC-3) and 21 A at 480 V, this reversing contactor assembly handles reversing motor loads up to those thresholds. At 575/600 V it is rated 20 hp, and at 460/480 V it carries 15 hp — the power rating shifts with the supply voltage. The maximum switching frequency under AC-3 duty is 750 operations per hour, and the same figure applies for AC-3e. This limits how often the contactor can reverse a motor in cyclic applications without exceeding thermal design margins. Mechanical life of the contactor is rated at 10,000,000 operations typical — the electrical life under full load will be lower and depends on the switching current and voltage.
Mounting, wiring, and panel fit
Dimensions are 90 mm wide, 101 mm high, and 97 mm deep — the S0 frame size. The depth of 97 mm is the dimension from the DIN rail mounting surface to the front of the assembly; account for this when planning gland-plate clearance and door swing. The magnet coil also terminates to screw-type terminals.
Environmental and mechanical withstand
This covers most indoor industrial panel environments but note the upper operating limit of 60 °C — derating may apply if the panel internal ambient exceeds this. Shock resistance is specified at 13.5 g / 5 ms and 8.3 g / 10 ms for AC, and 15 g / 5 ms and 10 g / 10 ms for DC. These values are relevant for applications mounted on machinery subject to vibration or impact events. The assembly includes 2 instantaneous auxiliary contacts. One contactor is supplied per direction of rotation; the supplied contactor MPN is 3RT2026-1AL20.
