LYD-40 Surge Protective Device
Short Description:
LYD-40 series spark gap power surgeprotector is designed and manufactured according to IEC61643-11 and GB18802.1standards. The product has high lightning current discharge capacity, up to50kA (10 350μS), which can prevent direct lightning strikes and other surgecurrent. This product can be mounted on a standard 35mm DIN rail mounting, ithas high safety factor and long service life, it can be applied to single-phaseor three-phase power supply in the class I lightning protection of equipmentand power system with high lightning risk.
