Both ends terminate in HAN Q8/0 connectors, one pin, one socket, so the cable is ready to plug into a drive or distribution box without field wiring. Length is specified at order time in 10 cm increments, within a range greater than 5 meters and less than 10 meters. That means you commit to a fixed length per cable; there is no field-adjustable slack, so measure the exact routing path before ordering. Because the cable is built to a specified length, it is a made-to-order item. For volume purchases or blanket orders, the commercial team can provide a schedule agreement. ## Integration Notes The HAN Q8/0 connector is a standard industrial rectangular interface, common on Siemens ECOFAST motor starters and distribution blocks. The 7-core, 2.5 mm² construction supports the power and control wiring for a typical motor branch — three phases, PE, plus two auxiliary conductors for brake or feedback. Specify the length in 10 cm steps when ordering. The cable is prefabricated at both ends, so the connector exit points are fixed; plan the gland plate entry and cable tray routing to avoid a tight bend radius at the connector backshell.","metaTitle":"Siemens 3RK1911-0CF40 ECOFAST Power Supply Cable, 7x2.5 mm²,","metaDescription":"Siemens 3RK1911-0CF40 ECOFAST power supply cable, 7 x 2.5 mm², prefabricated with HAN Q8/0 connectors.
