The Siemens 3RK1911-0BK10 is an ECOFAST motor connection cable — 11 conductors of 1.5 mm² each, cut to 1.5 m and terminated with a Han 10E connector on both ends. It is a pre-assembled drop-in cable for connecting motors to drives or junction boxes in the SIRIUS ECOFAST system, saving field-wiring time on the panel floor or at the machine.
What the spec means for fit
The 11 x 1.5 mm² conductor count and 1.5 m length tell you this is sized for a standard motor connection — typically 3 phases + PE + brake + encoder or thermistor lines, all in one jacket. The Han 10E connector on both ends means it mates directly to compatible ECOFAST receptacles on the drive and motor, no field termination needed. That saves stripping, crimping, and testing on site — fix it where it sits. Because it is pre-assembled, the cable is a fixed length with no service loop. Verify the 1.5 m span clears the cable path between drive and motor before committing the BOM line — too short and you are splicing, which defeats the purpose.
