This cable assembly is part of the ECOFAST connector system used in Siemens distributed I/O and motor starter architectures, designed for quick installation in control cabinets or junction boxes where pre-terminated cabling reduces field wiring time and error risk. ## Deployment Context The preassembled HAN Q4/2 and HAN Q8 connectors mate directly with ECOFAST distribution boxes and motor starters, making this cable a drop-in replacement for a subsegment line in a Siemens AS-Interface or PROFIBUS remote I/O network. The 5 x 4 sqmm conductors support power and signal distribution in a single jacket, suitable for routing within cable trays or conduit to a remote field station. The 10m to 15m length range covers typical distances from a central cabinet to a sub-distribution point.","metaTitle":"Siemens 3RK1911-0CR51 ECOFAST Subsegment Cable, 5x4 sqmm, 10","metaDescription":"Siemens 3RK1911-0CR51 ECOFAST subsegment cable assembly, 5x4 sqmm, 10m to 15m, HAN Q4/2 supply side to HAN Q8, preassembled both ends.
