What This Cable Is and Where It Fits
The Siemens 3RK1911-0CF30 is an ECOFAST power supply cable, 7 x 2.5 mm², prefabricated at both ends with a HAN Q8/0 connector (pin/socket). It is designed for quick, tool-free connection of power to distributed field devices in an ECOFAST I/O system — common on conveyor, material-handling, and assembly lines where multiple sensors and actuators share a common power trunk.
