This cable is used in the ECOFAST distributed installation system for motor and actuator power distribution in industrial automation, typically connecting a subsegment distributor to a motor or a downstream device in a daisy-chain topology. ## Physical and electrical construction The cable uses 5 x 4 mm² conductors, sized for the power supply of a small motor or a group of actuators within an ECOFAST subsegment. The 3M to 5M length covers typical distances between a subsegment distributor and the first device on the branch. Preassembled HAN Q4/2 (supply side) and HAN Q8 (load side) connectors eliminate field wiring time and reduce the risk of pin-out errors in a panel or junction box.","metaTitle":"Siemens 3RK1911-0CR31 ECOFAST Subsegment Cable, 5x4 mm², 3M-","metaDescription":"Siemens 3RK1911-0CR31 ECOFAST subsegment cable, 5x4 mm², 3M-5M length, HAN Q4/2 supply side, HAN Q8 connector, preassembled both ends.
