The Siemens 3RK1911-0CC20 is an ECOFAST power supply cable, 5 x 4 sqmm, prefabricated at both ends with HAN Q8/0 (pin/socket) connectors. It is ordered to any length under 3 m, specified in steps of minimum 10 cm. This is a field-wiring replacement or new-install cable for Siemens ECOFAST distribution systems — the kind you keep one in the cabinet for a line that cannot afford downtime waiting on a custom cut.
Deployment Context
The HAN Q8/0 (pin/socket) connectors on both ends mate directly to ECOFAST distribution boxes or motor starters in a control panel. The 5 x 4 sqmm conductor cross-section carries power to multiple loads downstream — sized for the branch circuit, not a single device. Specify the exact length when ordering; a 10 cm increment means you can trim panel routing without excess coil.
