Product details

Depth is 76 mm, height 90 mm. Sealable cover, halogen- and silicon-free construction. IP20 with conductors connected. Rated operating voltage 400 V AC; DC rated 60 V (max 72 V). Suitable for mechanical engineering and general industrial distribution per IEC/EN 60898-1, IEC/EN 60947-2, and UL1077. That's another SKU that crosses borders without rewiring the BOM.
