Product details

It is rated for AC-2 motor duty at 5.5 kW on a 400 V supply, with a maximum AC-12 resistive switching current of 10 A.

Ratings and coordination

The AC-12 resistive rating of 10 A covers heater or lighting loads. Short-circuit protection requires a gL/gG fuse: 20 A for type 2 coordination (no welding after fault), 35 A for type 1 (welding allowed but no fire risk). The coil is DC-operated with a closing and holding power of 3.3 W, rated at 220 V DC.

Termination and mounting

Screw terminals accept solid or finely stranded conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²). AWG equivalents for main contacts are 2x (20 to 16), 2x (18 to 14), or 1x 12. Maximum installation altitude is 2 000 m above sea level.

Frequently asked questions

What are the key ratings of 3RT1317-1BM40?

It is a size S00 power contactor with 4 NO main contacts, rated 5.5 kW at 400 V AC-2 (motor duty) and 10 A AC-12 (resistive). The coil is 220 V DC, 3.3 W. Dimensions are 45 x 57.5 x 72 mm.

How does 3RT1317-1BM40 compare to 3RT1016-1AG61?

Both are SIRIUS power contactors in size S00, but 3RT1317-1BM40 has 4 NO main contacts versus the 3RT1016-1AG61's 3 NO + 1 NC configuration. The 3RT1317-1BM40 also uses screw terminals; the 3RT1016-1AG61 may differ in terminal type or coil voltage. Panel footprint and DIN rail mounting are identical, so it can drop into the same slot, but verify the auxiliary contact arrangement and coil voltage before swapping.

Where can I buy 3RT1317-1BM40 and how is it quoted?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What compliance documentation is available for 3RT1317-1BM40?

As a current Siemens SIRIUS catalog item, it carries CE marking, UL/CSA recognition per IEC 60947-4-1, and RoHS/REACH declarations. The manufacturer provides a declaration of conformity on request.
