Siemens 3RK1911-0BA40 ECOFAST Power Cable, 5x4sqmm 10m HAN Q

The 3RK1911-0BA40: The 5 x 4 sqmm conductor cross-section handles up to roughly 32 A per conductor (depending on derating and ambient), which is typical for feeding multiple loads from a single ECOFAST tap. The 10 m length suits medium-span runs from the distribution box to the first load cluster — long enough to reach across a machine cell, short enough to avoid excessive voltage drop at 24 VDC. The single-side HAN Q8/0 connector plugs directly into the ECOFAST distributor; the unterminated end is field-wired into the load, so plan for a junction box or gland entry at the far end.
