Solar Shield Top provides a vented area on top of the enclosure to absorb solar heating effects and help keep enclosure cool. Also provides a drip shield to keep liquids away from the door sealing surface. Maintains enclosure rating. Includes mounting hardware. Shielding Effectiveness nVent HOFFMAN's research of the effects of solar radiation on enclosures has shown the positive benefits of utilizing shielding to decrease temperature rise. Shielding has been found to be an effective, low-cost method of reducing solar heat gain in outdoor electrical/electronic applications. Test results indicate that a top-mounted solar shield provides a 25 percent reduction in temperature rise due to solar heat load.
