At 110 V rated value, the contactor breaks 1 A (DC-1), and at 24 V it breaks 10 A. For AC loads, the AC-12 rating at 400 V hits 10 A, suitable for resistive or lightly inductive circuits. ## Coordination and short-circuit protection With type 2 coordination (no-weld after fault), the upstream fuse must be gL/gG 20 A. Type 1 coordination allows a 35 A gL/gG fuse — acceptable where a welded contactor is swapped after a fault rather than clearing clean. Side-by-side mounting is permitted — no derating for adjacent units. The screw-type terminals for the main circuit accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or up to 2x (0.75 to 4 mm²) solid or finely stranded with core-end processing. AWG equivalents: 2x (20 to 16), 2x (18 to 14), or single 12 AWG.","metaTitle":"Siemens 3RT1317-1BF40 SIRIUS Contactor, 110 V DC Coil, 4 NO,","metaDescription":"Siemens 3RT1317-1BF40 SIRIUS power contactor, size S00, 4 NO main contacts, 110 V DC coil, 5.5 kW at AC-2 400 V.
