Specification

®
Leviton offers a broad range of SPDs for almost any requirement. Many of our surge panels have easily replaceable
modules, which dramatically reduces maintenance costs. Additionally, Leviton SPDs are offered in many different
enclosure styles, with a variety of options such as surface or flush mounting and an optional surge counter.
All Leviton SPDs incorporate large MOVs as opposed to lower cost small MOVs in parallel. Large MOVs offer an
improved surge current rating and greater reliability, which ensures that the product will perform for many years.
Finally, Leviton’s world-class service team will provide on-site application support on an as-needed basis.
