This is the drop-in replacement cable for an ECOFAST motor interface; you swap it as a unit, no field wiring or crimping. Because this is a fixed-length, connectorized assembly, lead time depends on the Siemens production schedule for ECOFAST harnesses — not a standard off-the-shelf cable reel. ## What the construction means for fit The 4 x 2.5 mm² power cores handle the motor current; the 4 x 0.75 mm² signal cores carry brake, encoder, or thermal sensor feedback. The HAN 10E connector (industrial rectangular, 10-pin) is preassembled at both ends — male on one side, female on the other — so the cable plugs directly between the ECOFAST motor and the interface module. The 5-meter fixed length means you size the cable route before ordering; there is no field-cut option.","metaTitle":"Siemens 3RK1911-0BU30 ECOFAST Motor Connection Cable, 5 m","metaDescription":"Siemens 3RK1911-0BU30 ECOFAST motor connection cable, shielded 4 x 2.5 mm² + 4 x 0.75 mm², preassembled HAN 10E both ends, 5 m fixed length.
