Construction and fit
The 3RK1911-0CE20: The cable uses 7 x 2.5 sqmm conductors, which is a common power and signal conductor size for ECOFAST distribution blocks in Siemens ET 200 and AS-Interface systems. The HAN Q8/0 connector is a standard industrial rectangular interface; the Power T end mates with the ECOFAST power distribution tap. When ordering, specify the exact length in 10 cm increments — the factory prefabricates both ends, so the cable arrives ready to plug in, no field stripping or crimping required.
