The 3RK1911-0BB40: Five 4 sqmm cores means it carries the motor power and brake circuit in one jacket — common on Siemens ECOFAST motor/gearbox assemblies where the power and holding brake share a single cable run. The HAN Q8/0 is the rectangular industrial connector at the motor end; the Power T is the field-attachable tee that splits the line to the next drive in a daisy-chain. At 10 meters it's sized for a typical conveyor segment or machine axis where the drive cabinet sits a moderate distance from the motor.
