Cable construction and ordering
The 3RK1911-0CX30 is a Siemens ECOFAST motor connecting cable, shielded, with 4x2.5 sqmm power conductors and 4x0.75 sqmm signal/brake conductors, preassembled both ends with HAN 1NC (ST/BU) connectors. It's configured for delta connection.
Integration notes
This is a factory-terminated cable assembly — no field wiring of the HAN connector. The 4x2.5 sqmm power pair handles motor current; the 4x0.75 sqmm pair covers the brake and temperature sensor回路. Shield construction suits variable-frequency drive applications where EMI coupling to feedback lines is a concern.
