DEHNguard EZ50-S surge protectors from AutomationDirect are designed to withstand the harshest outdoor elements, keeping your systems running uninterrupted. This versatile unit supports multiple power configurations, including 3-phase wye, 3-phase delta, split-phase, and single-phase. It’s equipped with clear positive visual indicators—green means proper function, red means replace—so status checks are quick and reliable. The EZ50-S comes pre-wired with 36-inch leads, simplifying installation. Mounting is flexible, featuring a gasketed half-inch chase nipple and locknut for direct panel connection, as well as external brackets for panel or wall mounting. With a powerful 50 kiloamp maximum surge rating and a 200 kiloamp short-circuit current rating, along with field-replaceable and hot-swappable plug-in modules, this SPD is built for long service life. Housed in a rugged NEMA 4X enclosure, the DEHNguard EZ50-S delivers high-performance surge protection wherever it’s needed most. Learn all about them at AutomationDirect.com
