Product details

It mounts on a 35 mm DIN rail per DIN EN 60715 using either screw fixing or snap-on, and can be rotated ±180° on a vertical surface or tilted ±22.5° forward/backward.

Integration into a panel

The S0 frame measures 45 mm wide by 85 mm high by 97 mm deep, so it fits a standard 45 mm DIN-rail slot with 6 mm clearance at the side and 10 mm clearance in all other directions. Wire termination uses screw-type terminals on the magnet coil and accepts solid or stranded conductors from 1 to 10 mm², or two conductors of 0.5 to 2.5 mm².

Frequently asked questions

What is the closest functional second-source to the 3RT2026-1AT60?

The 3RT2026-1AG20 is a peer in the same SIRIUS S0 family. The main difference is the coil voltage; the 1AT60 uses a different coil rating than the 1AG20. Verify coil voltage compatibility before substituting.

What are the key ratings of the 3RT2026-1AT60?

It is a SIRIUS power contactor in S0 size, with auxiliary contacts rated 10 A at 24 V and 21 A at 480 V. It mounts on 35 mm DIN rail and accepts 1–10 mm² conductors.
