It's built for the ECOFAST connector system used in Siemens distributed automation and motor management applications, carrying power to remote I/O blocks, motor starters, or actuator/sensor interface modules. The cable length is specified between >3 m and <5 m, and orders must be placed in a minimum grid of 10 cm increments. The HAN Q8 connector is a rugged, industrial-grade rectangular interface rated for repeated mating cycles in control cabinet and machine-mount environments. Given the length-specific nature of the assembly (3-5 m, 10 cm grid), confirm the exact cable length needed when specifying — the factory cuts and terminates to the ordered length. ## Integration notes The HAN Q8 connector on both ends means this cable drops into an ECOFAST system without field-wiring — plug the Q8 into the compatible device-side receptacle and the power supply-side bulkhead. The 5 x 2.5 mm² conductor count supports three-phase power plus PE, or a mixed power/control bundle depending on the application. Because the cable is preassembled and length-specific, panel layout and cable routing must be finalized before ordering. The 2.5 mm² cross-section handles typical motor and I/O supply currents in distributed automation architectures; check the connected device's current draw against the cable's ampacity for the installed length.","metaTitle":"Siemens 3RK1911-0CQ50 ECOFAST Power Cable Interface, 5x2.5 m","metaDescription":"Siemens 3RK1911-0CQ50 ECOFAST power cable interface, 5x2.5 mm², preassembled HAN Q8 connectors both ends, 3-5 m length.
