Cable construction and ordering
The Siemens 3RK1911-0CB30 is a prefabricated ECOFAST power supply cable, 5 x 4 mm², terminated with a HAN Q8/0 connector on one end and a Power T connector on the other. The cable length is specified at time of order; the base part covers lengths greater than 3 m to less than 5 m, ordered in steps of minimum 10 cm. This is a field-assembly cable — the connectors are factory-molded, not field-wirable, so the length decision is final at order.
