Rated 25 A at 30 °C ambient (derated to 23.5 A at 40 °C, 21.75 A at 50 °C), so the real-world continuous current limit depends on enclosure temperature — in a warm panel at 40 °C, size the load to 23.5 A max, not the 25 A label. Width 36 mm (2 modular units), depth 77 mm, height 90 mm — snaps onto standard 35 mm DIN rail. Mounting position any orientation; supply feed from either top or bottom.
