The Siemens 3RK1911-0CP22 is an ECOFAST spur cable with 5 conductors of 6 mm² each, terminated at both ends with HAN Q4/2 connectors and preassembled to a length up to 3 m. This is the drop cable that connects a field device or junction box back to the ECOFAST trunk line in a modular machine-wiring scheme — the kind of pre-terminated assembly that saves panel-build time on repetitive runs.
Five conductors at 6 mm² each means this cable carries the power and signal pairs for a typical ECOFAST spur — enough cross-section for motor feeds up to the branch rating. The HAN Q4/2 connector is a rectangular industrial interface common on Siemens drive and I/O modules; preassembly at both ends eliminates field termination errors and cuts installation time on multi-drop lines.
