What this is
The 3RK1911-0BE40 is a Siemens ECOFAST power connection line — a pre-terminated cable assembly with 7 conductors of 2.5 sqmm each, cut to a 10 m length and fitted with a HAN Q8/0 connector on one end and a Power T on the other. This is the ready made-up variant, meaning it ships as a single piece, tested and dressed, for direct installation between an ECOFAST-compatible motor starter or distribution block and the load.
What it connects
The HAN Q8/0 industrial connector mates with the ECOFAST power distribution blocks used across the Siemens SIRIUS 3RK3 motor starter family and related modular safety systems. The Power T end typically feeds a motor or a downstream distribution point. The 7 x 2.5 sqmm conductor count handles three phases, neutral, PE, plus two auxiliary conductors — enough for a standard three-phase motor with brake or feedback, or for a dual-speed winding set.
