The 45 mm width and 57.5 mm height keep it compact for a 4-pole contactor; depth is 72 mm, which matters when you're planning gland-plate clearance or door swing in a shallow enclosure. Side-by-side mounting is allowed with no derating gap. Wire range on the mains accepts 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), or up to 2x (0.75...4 mm²) — fine-stranded with ferruled ends included. AWG equivalents are 2x (20...16), 2x (18...14), and 1x 12. ## Coil and switching specs The DC coil pulls 3.3 W on pickup and holds at the same 3.3 W — no power drop after sealing, so budget for continuous dissipation. Pickup voltage threshold is 0.85 x rated (20.4 VDC), dropout below that. Rated switching capacity across the auxiliary contacts: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, 6 A at 230 V, and 3 A at 400 V — all DC values. For the main circuit at AC-2, 400 V, it handles 5.5 kW. Mechanical life is typical 30 million operations. For type 2 coordination, the required upstream fuse is gL/gG 20 A; for type 1, 35 A.","metaTitle":"Siemens 3RT1317-1BB40 SIRIUS S00 Power Contactor, 24 VDC, 4","metaDescription":"Siemens SIRIUS 3RT1317-1BB40 power contactor, size S00, 24 VDC coil, 4 NO main contacts, 5.5 kW at AC-2 400 V.

Check your circuit's need for a normally-closed main pole before substituting — the 3RT1317-1BB40 gives you four NO paths, which matters for applications like star-delta or reversing starters where you need all poles to close together."},{"question":"What compliance documentation does Siemens provide for the 3RT1317-1BB40?","answer":"The part carries RoHS compliance with a substance prohibition date of July 1, 2006. It is designed to IEC 60947-4-1 and carries the reference code Q per IEC 81346-2.
