The Siemens 3RK1911-0BH20 is an ECOFAST motor connection line: 7 conductors, each 1.5 sqmm, in a 3-meter ready-made-up cable with a double-sided HAN 10E connector. It's a pre-terminated power cable for connecting a motor to an ECOFAST distribution box or drive interface — no field wiring, no terminal strip, just plug and run. The 7 x 1.5 sqmm conductor count covers a three-phase motor plus brake and thermistor or encoder feedback in a single jacket. The 3-meter length suits it for close-coupled motor mounts inside a machine frame or on a conveyor section.
Deployment context
The ECOFAST system is Siemens' modular, pre-wired motor connection solution for distributed drive topologies. This cable mates a motor's HAN 10E socket to the ECOFAST distribution box, common in conveyor, packaging, and material-handling lines where quick disconnect and IP-rated connections are required.
