It comes preassembled with a HAN Q8 connector on both the supply (ST) and distribution (BU) sides, using 5 x 2.5 sqmm conductors. The cable length is specified between 3 m and 5 m, ordered in a minimum grid of 10 cm increments. ## What the Description Means for Fit The ECOFAST system is Siemens' preassembled cabling for ET 200X, designed to cut field wiring time on conveyor, material-handling, and process lines. A HAN Q8 connector on both ends means this cable plugs directly into the interface module and the downstream distribution box — no field termination, no pinning errors. The 5 x 2.5 sqmm conductor size handles the power supply feed for a cluster of I/O modules or small motor starters in the ET 200X family.","metaTitle":"Siemens 3RK1911-0CS40 ECOFAST Power Cable Interface, Current","metaDescription":"Siemens 3RK1911-0CS40 ECOFAST power cable interface for ET 200X. 5 x 2.5 sqmm, HAN Q8 both ends, 3-5 m length.
