The Siemens 3RK1911-0BC40 is a pre-terminated ECOFAST power connection line: 5 x 4 sqmm conductors, 10 meters long, with Han Q8/0 connectors on both ends. It's a ready-to-run cable assembly for distributing power to field devices in an ECOFAST I/O system — no field wiring, no connector crimping.
Deployment context
This cable connects an ECOFAST power distribution module to a remote actuator or sensor cluster in a 24 VDC control cabinet. The Han Q8/0 industrial connector is rated for the 4 sqmm conductor cross-section, so it handles the current draw of multiple solenoid valves or I/O blocks without excessive voltage drop over the 10 m run.
