DS40HF Surge Protectors are designed for primary surge protection AC networks. They provide common-mode protection (between the active conductors and ground). A specific RFI filter is added in order to suppress high frequency disturtances. The DS4xHF is DIN rail compatible and is built with a plug-in module and a fixed base, which allows a easy and fast maintenance.
