The Siemens 3RK1911-0BD30 is an ECOFAST power connection line — a pre-assembled, molded cable assembly with 7 conductors of 2.5 sqmm each, terminated on one end with a HAN Q8/0 connector and cut to a 5 m length. This is a ready-to-install drop for power distribution in Siemens ECOFAST systems, commonly used in motor control centers and decentralized field-level power distribution where a single cable carries both power and control conductors to a remote station.
The 7 x 2.5 sqmm conductor count and cross-section tell you this cable is sized for moderate power distribution — 2.5 sqmm copper handles up to roughly 20–25 A per conductor in a multicore bundle (derated for grouping), which suits the feed to a small motor starter or a remote I/O cabinet. The 5 m length is a standard drop for panel-to-machine wiring within a typical cell. The HAN Q8/0 single-side termination means the connector is factory-molded on one end; the other end is unterminated, ready for field wiring into a terminal block or a second connector. This saves panel-build time versus field-assembling a HAN connector.
Deployment Context
This cable is part of the Siemens ECOFAST system, a modular, pre-wired power distribution architecture for industrial control panels. It connects directly to ECOFAST distribution blocks or motor starters, eliminating point-to-point wiring. The molded HAN Q8/0 connector provides IP65/67-rated sealed connection at the distribution point, suitable for washdown or dusty environments in food-and-bev, automotive, or material-handling lines.
