Siemens 3RK1911-0AG70 is an ECOFAST power bus cable, 5 x 4 sqmm, supplied on a 50m reel and sold by the meter. This is the bulk power distribution cable for the ECOFAST connector system, used to daisy-chain 24 VDC and 230 VAC supply along a machine line without individual field wiring to each sensor or actuator node.
The 5 x 4 sqmm cross-section supports the full ECOFAST system current rating over the 50m reel length. Sold by the meter, so you order only what the run needs — no leftover coil on the shelf. Common deployment: linking power supply modules to ECOFAST distribution boxes on conveyor, packaging, and material-handling lines where IP65/67 rated quick-connects replace terminal blocks.
