How can you prevent UV damage to outdoor electrical enclosures?
Short answer
To prevent UV damage to an outdoor electrical enclosure, specify a UV-resistant material and shelter the installation wherever possible. UV radiation degrades the materials used in standard enclosures, which can in turn affect the internal electronic components and cause failures and operational disruption. Ideally, mount the enclosure on the sheltered side of a building, away from direct sunlight and the worst of the elements. Our GEOS industrial and outdoor range is constructed from high-grade polycarbonate and is highly resistant to UV radiation and harsh weather; it has passed the 1000-hour weathering test to DIN EN ISO 4892-2 and the UL 746C weathering tests.
UV radiation can do significant damage to standard electrical enclosures, so the two things that matter most outdoors are the material you specify and where you put it. Without proper protection, the materials used in the enclosure degrade, and that can have a serious impact on the internal electronic components, potentially causing failures and operational disruption.
The location of your installation plays an important role. Ideally, the enclosure should be installed on the sheltered side of a building, protecting it from direct sunlight and the worst of the elements and helping to prolong the life and integrity of your enclosures.
Understanding the importance of reliable protection outdoors, we offer the GEOS range of industrial and outdoor enclosures: https://www.spelsberg.com/geos-industrial-and-outdoor-enclosures/. Our GEOS enclosures are constructed from high-grade polycarbonate, making them highly resistant to UV radiation and harsh weather conditions.
If you need a tailored solution, you can configure an enclosure to your own specific requirements on our GEOS configurator page: https://configurator.spelsberg.com/spelsberg/html/#/home?lang=en. A free ‘myspelsberg’ membership, available at https://www.spelsberg.co.uk/service/myspelsberg/, lets you save, load and manage your configurations.
GEOS enclosures have successfully withstood rigorous testing, including the 1000-hour weathering test according to DIN EN ISO 4892-2 (formerly DIN 53 387) and the UL 746C weathering tests, ensuring they meet the highest standards of durability and functionality.
