Product details

It mounts via screw and snap-on onto 35 mm DIN rail per DIN EN 50022, and the main circuit uses spring-loaded terminals accepting 2x (0.25... 2.5 mm²) solid or stranded wire. The coil is rated 110 VDC, and the contactor carries DC switching ratings across a range of voltages: 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, and 0.8 A at 440 V. That means for a 24 VDC load you can switch up to 10 A; at 110 VDC the limit drops to 1 A.

The mounting position allows vertical surface mounting with +/-180° rotation and +/-30° tilt front-to-back.

Frequently asked questions

What is the depth of 3RT1516-2BF40?

The depth is 72 mm.

What wire size does the spring-loaded terminal accept?

It accepts 2x (0.25... 2.5 mm²) solid or stranded wire.

Will 3RT1516-2BF40 drop into a panel specified around 3RT1016-2AP02?

Both are size S00 contactors on the same DIN-rail footprint, so the mechanical fit is the same. The main difference is the coil voltage — 3RT1516-2BF40 uses 110 VDC, while 3RT1016-2AP02 uses a different coil. Verify the coil supply before swapping.

Where can I buy 3RT1516-2BF40?

This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
