Product details

It snaps onto a 35 mm DIN rail per DIN EN 50022 and uses spring-loaded terminals accepting 2x (0.25 to 2.5 mm²) solid or stranded wire — no screwdriver needed for termination.

DC switching profile

Rated DC-1 switching current drops with voltage: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V. The arcing time spans 7 to 15 ms depending on load inductance — plan for a snubber if switching motor brakes or solenoid valves at the higher voltage end.

Panel fit

Footprint is 45 mm wide, 60 mm tall, 72 mm deep. The IP20 finger-safe terminals and front face keep it clean inside a standard enclosure.

Frequently asked questions

Where can I buy 3RT1516-2BA40 and get a price?

Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.

What is the closest functional second-source for 3RT1516-2BA40?

The 3RT1016-2AP02 is a size S00 SIRIUS contactor with a similar 24 VDC coil and spring-loaded terminals, but it uses screw-type main terminals and has a slightly different DC switching curve — verify your load voltage against both datasheets before substituting.

What wire sizes does the spring-loaded terminal accept?

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

What is the depth of 3RT1516-2BA40?

Depth is 72 mm.
