It ships as a complete unit: three contactors (two 3RT2027-1AL20 and one 3RT2026-1AL20) plus the RS assembly kit 3RA2923-2BB1, all pre-mounted and wired on a common base plate. ## Mounting and panel integration The vibration resistance is 13.5g / 5 ms and 8.3g / 10 ms for AC, 15g / 5 ms and 10g / 10 ms for DC — this matters for installations on machinery with shock loads. RoHS compliance date is noted as 10/01/2009, indicating the part meets the EU RoHS directive from that date forward.","metaTitle":"Siemens 3RA2426-8XF32-1AL2-ZX95 SIRIUS Star-Delta Starter","metaDescription":"Siemens SIRIUS 3RA2426-8XF32-1AL2-ZX95 star-delta contactor assembly, 22 kW at 400 V, S0 frame.
