This is a ready-to-run cable assembly for Siemens ECOFAST distributed I/O and motor starter systems — pull it out of the box and bolt it into the field junction box. The 7 x 2.5 sqmm conductor count and cross-section tell you this cable carries three-phase power plus PE plus two auxiliary/signal conductors — enough for a motor starter with brake control or a small distributed I/O node. The 2.5 sqmm per conductor is sized for 16-20 A continuous at 400 VAC, matching the typical output of an ECOFAST motor starter. The HAN Q8/0 connector on both ends means it mates directly into the ECOFAST system's power distribution box and the motor starter or I/O module — no field wiring, no terminal strip. The 10-meter fixed length covers the span from the distribution cabinet to the first field device in most machine cells; if your run is longer, you need a different order code in the 3RK1911 family. This cable belongs in a Siemens ECOFAST distributed automation installation — typically on conveyors, packaging lines, or material-handling systems where motor starters and I/O blocks are mounted in the field rather than in a central cabinet. The double-sided HAN Q8/0 connectors make it a plug-and-play link between the power distribution box and the field device, cutting installation time versus running individual wires through conduit. ## Sourcing Reality The lifecycle stage is current.","metaTitle":"Siemens 3RK1911-0BF40 ECOFAST Power Cable, 10m HAN Q8/0","metaDescription":"Siemens 3RK1911-0BF40 ECOFAST power connection line, 7 x 2.5 sqmm, 10m length, double-sided HAN Q8/0.
