RPH320-50/3N+NPE belongs to class I three-phase power surge
protector, which has large current capacity, strong adaptability to
power grid, safety and reliability. It can be widely used in
various electrical occasions. It can be used in the distribution
system from LPZ0 to LPZ1, which can prevent the back electrical
equipment from being damaged by lightning and transient
overvoltage.Features:The three-phase power surge protector adopts a
variety of lightning protection device combination protection
modes, parallel and multi-functional integrated design, and has the
functions of working state indication and failure remote
alarm.1.Parallel, multi-functional modular design, using 3 + 1
mode, which can be applied to TN and TT power grids.2.High
performance lightning protection devices are adopted, with strong
freewheeling breaking ability and no freewheeling.3.Safe and
reliable, fully sealed design, no flashover.4.Low voltage
protection level and large flow.5.Exquisite craftsmanship, able to
work for a long time in harsh
environments.ModelParameterRPH320-50/3N+NPEApplicationL-N,
