It's specified for any length between >5m and <10m, ordered in steps of minimum 10cm — so you tell us the exact run and we'll quote that cut. ## What the cable is for This is a pre-made power supply cable for Siemens ECOFAST distributed I/O and motor starter systems — the kind you'd run from a central power distribution block out to a remote cabinet or a motor control center on a conveyor line or pump station. The 5 x 4 sqmm conductor cross-section handles the load current for several downstream devices. The HAN Q8/0 connector at one end plugs directly into the ECOFAST bus interface module; the other end is unterminated, so you pull it through cable tray and land it in your own terminal block or junction box. No field-wiring of the connector — just strip and terminate the free end.","metaTitle":"3RK1911-0CA40 ECOFAST Power Supply Cable, 5x4 sqmm, HAN Q8/0","metaDescription":"Siemens 3RK1911-0CA40 ECOFAST power supply cable, 5 x 4 sqmm, prefabricated one end HAN Q8/0, 5m to <10m.
