Product details

The main circuit uses screw-type terminals accepting 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid or stranded wire. Auxiliary contacts are rated 9 A per NC and per NO contact.

DC switching capability

This contactor is rated for DC switching across several 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. The operate time on DC is 7 to 10 ms, and arcing time runs 10 to 15 ms — useful when sizing suppression for inductive DC loads like brake coils or solenoid valves.

Mounting position allows +/-180° rotation and +/-30° tilt on a vertical surface. Pickup threshold 0.85 of rated control voltage; dropout 1.1 of rated. IP20 on the front and at the terminals means finger-safe touch protection; suitable for enclosed panels where no washdown or dust ingress is expected.

Frequently asked questions

What is the depth of 3RT1516-1BM40?

The depth is 72 mm.

What wire sizes does the 3RT1516-1BM40 accept?

The screw terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid or stranded conductors.
