Product details

The Siemens 3RT1316-1BP40 is a SIRIUS power contactor in the compact Size S00 frame — 45 mm wide, 57.5 mm tall, 72 mm deep — designed for switching motor loads in control panels. 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.

Frequently asked questions

Where can I buy 3RT1316-1BP40 and how do I get a price?

This contactor is sourced to order against an RFQ through independent distribution. Submit a request for quote to confirm current availability and pricing — no stock figures or firm price are published here.

What is the difference between 3RT1316-1BP40 and the 3RT1016-1AR11?

The 3RT1316-1BP40 is a Size S00 contactor with 4 NO main contacts and screw terminals, rated 4 kW 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.

What is 3RT1316-1BP40's listed depth?

The depth is 72 mm from the mounting surface to the front of the enclosure, fitting standard 80 mm deep enclosures with clearance.

What wire sizes does the 3RT1316-1BP40 accept?

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.

Will 3RT1316-1BP40 drop into a panel specified around 3RT1016-1AR11 without rewiring?

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.
