Product details

Its 24 VDC coil draws 10 A at rated voltage, so the coil-holding current is what you budget for in your 24 VDC supply — not the main contact rating. Main circuit termination uses spring-loaded terminals, accepting 2x (0.25... 2.5 mm²) solid or stranded wire. That means no screw-torque checks on the line — just strip to 8 mm and push in.

The mounting position is flexible: vertical surface with +/-180° rotation, or +/-30° tilt front-to-back. That covers most panel layouts — upright, rotated 90°, or tilted in a sloped enclosure. Dimensions are 45 mm wide, 60 mm high, 72 mm deep. At 45 mm, it occupies a single 45 mm DIN-rail module width — standard for size S00 contactors.

Frequently asked questions

What are the key ratings for this contactor?

The coil is rated 10 A at 24 VDC. The main circuit is spring-loaded terminals accepting 2x (0.25... 2.5 mm²). It mounts on 35 mm DIN rail, size S00 frame, with an IP20 front. Operating temperature is -25 to +60 °C.

Will the 3RT1516-2BP40 drop into a panel designed for the 3RT1016-2AP02 without rewiring?

Both are size S00 contactors on a 35 mm DIN rail, so the footprint and rail position are the same. The 3RT1516-2BP40 uses spring-loaded terminals, while the 3RT1016-2AP02 may use screw terminals — the wire entry points are in the same locations, but you will need to confirm the terminal type matches your existing wiring method. No rewiring of the panel layout is required.
