Product details

At 45 mm wide and 72 mm deep, it fits a standard S00 footprint — no surprises on the gland plate.

The DC magnet coil draws 3.3 W on closing and holds at the same 3.3 W — a constant-hold design that simplifies the control transformer sizing. Rated control supply voltage is 42 V DC. The pick-up threshold is 0.85 x rated voltage (about 35.7 V), and the drop-out is not explicitly stated but typical for this class is around 0.6 x rated.

Switching capacity and coordination

Switching capacity at 24 V DC is 10 A, dropping to 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V — the inductive load curve typical for DC coils and solenoids. For AC-12 (resistive) use, the maximum operating current is 10 A. Short-circuit protection: with type 2 coordination, use a gL/gG fuse rated 20 A; with type 1, a 35 A fuse.

Frequently asked questions

What is the depth of 3RT1317-2BD40?

The depth is 72 mm, which fits the standard S00 contactor footprint on a 35 mm DIN rail.

What wire sizes does the 3RT1317-2BD40 accept?

The spring-loaded terminals accept 2x (0.25 to 2.5 mm²) solid or stranded wire, or 2x (24 to 14 AWG) for the main contacts.

Will 3RT1317-2BD40 drop into a panel specified around 3RT1016-2AP02?

Both are S00-size SIRIUS contactors on the same 45 mm wide footprint, so the mechanical fit and DIN-rail mounting are identical. The main difference is the coil voltage and contact configuration — verify those against your BOM before ordering.

Where can I buy 3RT1317-2BD40 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.
