This is the drop cable that runs from an ECOFAST distribution box or motor starter to the motor itself in a distributed drive architecture. The shielding is critical for keeping VFD-induced common-mode currents off the signal pair, which matters when the cable runs alongside power conductors in a cable tray or chain. The 4 x 2.5 mm² power conductors handle the motor current for a typical small-to-medium drive (up to around 5.5 kW at 400 V depending on cable length and ambient). The 4 x 0.75 mm² pair carries the brake control, temperature sensor (PTC/KTY), or encoder feedback — whatever the motor-integrated electronics need. The HAN 10E connector is a standard industrial rectangular interface; preassembled both ends means no field wiring, no pinning errors, and a consistent shield termination. This is a drop-in replacement for any ECOFAST node using the same connector pattern.","metaTitle":"Siemens 3RK1911-0CU20 ECOFAST Motor Connection Cable, Shield","metaDescription":"Siemens 3RK1911-0CU20 ECOFAST shielded motor connection cable, 4 x 2.5 mm² + 4 x 0.75 mm², preassembled HAN 10E connectors.
