Dear Robert,

There are a number of applications where electrical enclosure may be partially submerged, such as areas at risk of flooding. In these cases, an ingress protection (IP) rating equal to IP68 is recommended, as it ensures that the enclosure can resist prolonged immersion in at least one meter of water.

To address this requirement, it is possible to rely on extremely well specified components, such as gaskets, seals, hinges and lids. However, the most cost-effective yet reliable solution consists of utilizing silicone or resin protections within the enclosure. This material protects the internals by preventing the penetration of any form of moisture.

Spelsberg’s Abox XT series of junction boxes leverages this method to withstand submersion in up to 10 meters of water. More precisely, they come together with a cast resin bag and a funnel. To support the process, the enclosures feature two holes, one to pour the resin and the other to let all the air out. Once the gel sets, the boxes are ready for use, and can be combined with cable glands and other accessories.

This solution offers particular flexibility, supporting retrofitting and repurposing, as the casting resin can be easily removed, and new one can be applied afterwards.
