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
- Type 2 AC surge protector
- RFI Filtering
- In: 20 kA
- Imax: 40 kA
- Pluggable module
- Remote signaling option
- IEC 61643-11, EN 61643-11 and UL1449 ed.4 compliance
