Preassembled power cable interface for ET 200X
The Siemens 3RK1911-0CR20 is a preassembled ECOFAST power cable interface for the ET 200X distributed I/O family. It comes with HAN Q8 connectors on both the source (ST) and device (BU) sides, wired with 5 × 4 mm² conductors. Any cable length under 3 m is available, ordered in a 10 cm grid — so you specify the exact drop length, not a fixed catalog item.
Deployment context
The HAN Q8 industrial connector mates directly to the ET 200X interface module, making this a drop-in power cable for distributed I/O cabinets. The 5 × 4 mm² cross-section handles the motor and auxiliary supply currents typical of an ET 200X node. Because it is preassembled and tested at the factory, field wiring time drops to plugging in two connectors — no crimping, no pin mapping.
