Product details

It is rated for 4 kW at AC-2 duty on 400 V, making it suited for switching motor loads like pumps and conveyors in control panels. The DC magnet holds at 3.3 W, with a pickup threshold of 0.85 x rated voltage and an overexcitation limit of 1.1 x rated voltage.

The S00 footprint is compact at 45 mm wide, 57.5 mm tall, and 72 mm deep — leaves room on a crowded DIN rail for auxiliary blocks or overload relays. Screw-type terminals on the main circuit 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) max. AWG equivalents: 2x (20 to 16), 2x (18 to 14), 1x 12. Finely stranded conductors require core-end processing. Front and terminal protection is IP20.

Ratings and coordination

The DC coil operates over a 48 V nominal with a pickup threshold of 0.85 (40.8 V) and can tolerate 1.1 x (52.8 V) for overexcitation. Switching capacity on the DC side: 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, 3 A at 400 V. For AC-12 resistive loads, the maximum operating current is 10 A. Type 2 coordination requires 20 A. Maximum altitude is 2 000 m. Mechanical endurance is typical 30 million switching cycles. The contactor carries a reference code Q per DIN EN 81346-2.

Frequently asked questions

How do I get current pricing and availability for 3RT1316-1BW40?

Pricing and availability are confirmed at quote time. Submit an RFQ through this listing; the sourcing desk returns current landed cost and lead time tailored to your quantity and region.

What is 3RT1316-1BW40's listed depth?

The depth is 72 mm, with a width of 45 mm and height of 57.5 mm — the S00 frame size fits standard DIN-rail enclosures.

Will 3RT1316-1BW40 drop into a panel specified around 3RT1016-1AG61 without rewiring?

Both are S00 frame contactors with the same DIN-rail footprint and screw-terminal pattern, so mechanical fit is identical. However, verify the coil voltage — the 3RT1316-1BW40 uses a 48 V DC coil, while the 3RT1016-1AG61 may differ. The main contact configuration also differs: the 3RT1316-1BW40 has 4 NO contacts versus the 3RT1016-1AG61's 3 NO + 1 NC arrangement. Rewiring the auxiliary circuit may be required.

What compliance documentation does Siemens provide for 3RT1316-1BW40?

Siemens SIRIUS contactors carry CE marking and are designed to IEC/EN 60947-4-1. RoHS and REACH declarations are available through Siemens Industry Online Support. UL and CSA file numbers are typically listed on the nameplate for North American installations.
