The 10 A AC-12 rating covers resistive and solid-state loads for the same contact set. At 45 mm wide, this contactor fits four across a standard 600 mm-wide backpanel with room for gland plates. Side-by-side mounting is permitted, with 6 mm spacing at the side for heat dissipation. The screw terminals accept 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) stranded, or up to 2x 4 mm² with ferrules — a full range that covers control wiring and motor leads without adapters. The DC coil draws 3.3 W both on pickup and hold, so the control transformer and PLC output card see a constant load — no inrush spike to size for. For Type 2 coordination (contactor remains operational after a fault), drop to a 20 A gL/gG fuse.","metaTitle":"Siemens 3RT1316-1BP40 SIRIUS Power Contactor, Size S00, 4 NO","metaDescription":"Siemens SIRIUS 3RT1316-1BP40 power contactor, Size S00, 4 NO main contacts, 4 kW at 400 V AC-2.

The 3RT1016-1AR11 is also Size S00 but carries 3 NO + 1 NC main contacts and uses a different coil voltage — the physical footprint is the same, so it drops into the same DIN-rail location, but the contact configuration and coil differ, so verify your circuit's NC requirement before substituting."},{"question":"What is 3RT1316-1BP40's listed depth?","answer":"The depth is 72 mm from the mounting surface to the front of the enclosure, fitting standard 80 mm deep enclosures with clearance."},{"question":"What wire sizes does the 3RT1316-1BP40 accept?","answer":"The screw terminals accept 2x (0.5 to 1.5 mm²) solid, 2x (0.75 to 2.5 mm²) stranded, or up to 2x (0.75 to 4 mm²) with ferrules. AWG equivalents are 2x (20 to 16), 2x (18 to 14), and 1x 12."},{"question":"Will 3RT1316-1BP40 drop into a panel specified around 3RT1016-1AR11 without rewiring?","answer":"Both are Size S00 on the same 45 mm DIN-rail footprint, so the mechanical swap is direct. However, the 3RT1316-1BP40 has 4 NO contacts while the 3RT1016-1AR11 has 3 NO + 1 NC — if your circuit uses that NC contact, you'll need to rewire or add an auxiliary contact block. The coil voltage may also differ; verify before ordering."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT1316-1BP40","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RT1316-1BP40 when reusing this data.
