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 circuit. Shield construction suits variable-frequency drive applications where EMI coupling to feedback lines is a concern.","metaTitle":"Siemens 3RK1911-0CX30 ECOFAST Motor Cable, Shielded 4x2.5+4x","metaDescription":"Siemens 3RK1911-0CX30 ECOFAST motor connecting cable, shielded, 4x2.5 sqmm + 4x0.75 sqmm, preassembled HAN 1NC connectors both ends.
