WISKA UK proudly adds the COMBI 310 to its iconic COMBI Junction Box range, designed directly from customer feedback and engineered for performance, protection and durability.
At the heart of its innovation is a unique configuration of three M20 threaded membrane side entries, giving electricians greater ‑ flexibility for looping connections and cable management than ever before. Combined with IP66/67 protection, robust materials and time-saving features, the COMBI 310 sets a new benchmark for junction box design.
The COMBI 310 was born from a conversation between WISKA and the electrical community. Customers told us they needed a box that could handle looping connections more efficiently, specifically a 3 sided junction box for outdoor lighting installation – so we designed exactly that.
With 10 x M20 threaded membrane entries, 4 rear membrane entries, the COMBI 310 gives electricians the flexibility they need across a wide range of applications – from outdoor lighting systems, HVAC systems and industrial control panels to solar and renewable energy installations.
The COMBI 310 is designed for both indoor and outdoor use, delivering reliable performance in industrial, commercial or domestic environments. Whether it’s part of a larger installation or used as a standalone solution, the COMBI 310 offers versatility and resilience in equal measure.
For installations using Steel Wired Armoured (SWA) cables, the COMBI 310 can be fitted with a unique COMBI 310 earth bar mounted to the three M20 side entries, or our E-SPRING earthing springs allowing secure and compliant earthing directly within the enclosure.
Gel-Ready for Maximum Protection
The COMBI 310 is also fully compatible with WISKA Gel Range, including the MP One 300ml, which is the perfect quantity to fill the enclosure. Using the gel increases the protection rating from IP66/67 to IP68, making the enclosure suitable for underground or direct burial applications. This added capability ensures even greater longevity and reliability, especially in demanding or exposed environments.
The COMBI 310 is more than just a junction box – it’s the perfect harmony of form, function and feedback. Every curve, every feature and every entry point has been carefully considered to meet the needs of modern installers while upholding the proud heritage of the WISKA and COMBI Junction Box name.
