Wiska WI304 10110629 Round Enclosure Grey

The Wiska WI304, also known as the COMBI 304 LG (order number 10110629), is a round, light-grey (RAL 7035) electrical enclosure designed for both functional and aesthetic installations. With a diameter of 82 mm and a height of 57 mm, it offers a compact yet spacious design made from halogen-free, UV-resistant polypropylene, making it suitable for indoor and outdoor environments. The enclosure features four M20 membrane-threaded side entries that support cable diameters from 3 mm to 12 mm and circuits up to 400 V with conductor sizes up to 2.5 mm².

Rated IP66 by default, the box can achieve IP67 protection when fitted with compatible Wiska ESKV cable glands. A flat lid secures with a bayonet-style quarter-turn system, reinforced by a hook-locking mechanism that requires a tool to open—ensuring tamper resistance and reliable sealing. Internally, it provides around 180 ml of volume and comes without terminals, giving installers full flexibility for custom wiring solutions. It operates in temperatures ranging from –30 °C to 100 °C and meets a glow wire test rating of 750 °C, ensuring robust performance in demanding environments.
