Product details

DIN-rail fit and panel integration

Mounting position any orientation, fastens via the quick assembly system — snaps in without tools. IP20 with connected conductors; pollution degree 3 suits industrial enclosures where conductive dust or condensation is present.

Thermal derating and ambient limits

Rated 2 A at 35 °C; derates linearly to 1.7 A at 60 °C. Humidity derating applies above 55 °C — max 95% RH up to 55 °C, then 55% at 70 °C, 35% at 75 °C. For a warm panel or outdoor cabinet, factor the derated current into the load calculation.
