These hubs are designed to prevent water ingress into the safety switch enclosure. They typically include gaskets and are made from zinc or chrome-plated materials to resist corrosion. Water resistant hubs are field installed on NEMA Type 4/4X/5 stainless steel and NEMA Type 12/3R and 12K enclosures. This sealing capability ensures the switch remains operational and safe even in wet or humid environments.
