Wiska COMBI® 310 Junction Box

Weatherproof Connections: Wiska COMBI® 310 Junction Box

Outdoor electrical connections need proper protection to maintain reliability through British weather conditions. The Wiska COMBI® 310 junction box provides IP66/67 rated protection in a compact housing with practical features that speed up installation and future maintenance.

Compact Housing, Spacious Interior

The COMBI® 310 measures 118 × 85 × 51mm externally and is compact enough to fit in restricted spaces without being obtrusive.

Big news though… the interior provides 10% more space than previous versions, accommodating multiple connections without cramping cables or terminals. This extra space makes a genuine difference when you’re working with several cables entering from different directions. The compact external dimensions mean the box fits where larger enclosures won’t, while the spacious interior prevents the overcrowding that makes terminations difficult and increases the risk of connection problems. It’s a practical balance between size and usability.
