This is a ready-made cable assembly for distributing power to field devices in an ECOFAST system, common in Siemens ET 200 and SIMATIC distributed I/O installations. The 5 x 4 sqmm conductor cross-section tells you this line carries power — likely 24 VDC or 230 VAC at currents up to around 30-40 A depending on derating and ambient, though the exact ampacity depends on the cable type and installation method. The 3-meter fixed length means you need to plan the routing distance between the power distribution module and the field device or junction box; it's not field-cuttable to a custom length. The single-side HAN Q8/0 connector mates with the ECOFAST power distribution block; the other end is unterminated (stripped wires) for direct connection to the device or terminal block. Because the lifecycle stage is confirmed as current, this is a standard BOM line item — no urgency to stockpile or find a substitute. No official successor or cross-reference exists; the 3RK1911-0BA20 is the active order code for this specific cable assembly.","metaTitle":"Siemens 3RK1911-0BA20 ECOFAST Power Connection Line, 3m","metaDescription":"Siemens 3RK1911-0BA20 ECOFAST power connection line, 5x4 sqmm, 3m length, ready-made single-side HAN Q8/0.
