Product details

Rated 25 A at 30 °C ambient, it derates to 24 A at 40 °C and 23.5 A at 45 °C — per the datasheet, if the panel ambient runs above 30 °C, the continuous load must be reduced accordingly. IP20 with connected conductors protects against finger contact for dry indoor enclosures.

Integration notes for the panel builder

Single modular width (18 mm) fits standard cutouts. The neutral conductor is switched internally, so no separate neutral bar connection is needed downstream. Touch-protected terminals reduce risk during commissioning. Halogen-free and silicon-free construction meets the material restrictions common in rail, marine, and clean-room installations.
