What it is and what it does
The Siemens 3RK1911-0CP52 is an ECOFAST spur cable assembly, 5 x 6 mm² conductors, factory-terminated at both ends with HAN Q4/2 connectors, in a 10m to 15m length range. This is a preassembled drop cable for the ECOFAST field-distribution system — the HAN Q4/2 plug at each end means it connects a motor or actuator to the ECOFAST bus without field wiring or gland work.
