What it is and what it does
The Siemens 3RK1911-0CA20 is an ECOFAST power supply cable, 5x4 sqmm, prefabricated at one end with a HAN Q8/0 connector. It is designed to deliver power to ECOFAST distribution blocks and devices in a modular automation system, typically used in conveyor, material handling, and assembly lines where quick-connect power distribution is needed. The cable is supplied to any length specified when ordering, in steps of minimum 10 cm.
Integration note
The cable is prefabricated at one end only, so the field end must be terminated by the installer. The HAN Q8/0 connector mates directly with ECOFAST distribution blocks, which are DIN-rail mounted in control panels or junction boxes. When ordering, specify the exact length in 10 cm increments — the cable is cut and terminated to that length, so there is no excess to coil. The 5x4 sqmm cross-section supports the current-carrying capacity typical for ECOFAST power distribution in a 24 VDC or low-voltage AC control circuit.
