Cable Description and Ordering
The Siemens 3RK1911-0CF20 is an ECOFAST power supply cable with 7 conductors of 2.5 sqmm each, prefabricated at both ends with HAN Q8/0 connectors (pin/socket configuration). This is a custom-length cable: for runs under 3 meters, you specify the exact length when ordering, in increments of 10 cm minimum. The HAN Q8/0 industrial connector family is common in Siemens ECOFAST distributed I/O and motor starter systems, providing a standardized power tap for 24 VDC and AC supplies in the field.
What the Connector Means for Fit
The HAN Q8/0 interface is a 8-pin industrial rectangular connector (pin/socket variant) used across the Siemens ECOFAST product family for power distribution to AS-i modules, motor starters, and I/O blocks. If your panel or field junction uses the mating HAN Q8/0 receptacle (typically panel-mount or bulkhead), this cable plugs directly in — no adapter or field-wiring required. The 7 x 2.5 mm² conductor count supports both power and auxiliary circuits (e.g., 24 VDC load supply plus a separate PE and signal return) in a single molded assembly.
