Cable Assembly Overview
The Siemens 3RK1911-0CR51 is a preassembled ECOFAST subsegment cable with a 5 x 4 sqmm conductor cross-section, terminated at both ends: a HAN Q4/2 connector on the supply side and a HAN Q8 connector on the field-device side, in a length range of 10m to 15m. 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.
