Outdoor Sauna Main Module Waterproof Enclosure Kit

The Outdoor Sauna Main Module Waterproof Enclosure Kit is designed for outdoor sauna heater installations where the main heater control module, power unit, relay box, or extension module needs added protection from rain, dust, splash exposure, and humidity. This sauna-specific solution gives your electrician the enclosure and four IP68-rated cable glands needed for a cleaner, more professional installation—eliminating the guesswork of sourcing generic boxes and mismatched fittings. Low-voltage wiring routes neatly through the included glands, while line-voltage wiring should use electrician-supplied liquid-tight conduit and connectors. Common use cases include Harvia Xenio-style power units, HUUM-style main modules, extension modules, and relay boxes. Not intended for keypad-only protection. Approx. size: 13″ W × 16.93″ H × 7.09″ D. 

Important: The enclosure is supplied blank and must be drilled by the installer. Low-voltage cable entries should use the included IP68 cable glands. Line-voltage wiring must use appropriately rated liquid-tight conduit and connectors. Bottom entry is recommended whenever possible. Final weather resistance depends on proper installation of all cable glands, conduit fittings, and penetrations.
