Product Features
1.Strong protection ability: Max current flow is 150kA (8/20μs) with a low residual voltage, employing
high performance piezoresistor components and the inner metalic shield protective module, including
over current and over heating protection and temperature controlled by temperature controlle open circuit
technology inside technology, can realized Kevin connection.
2.Overall protection: OBV8 series SPD are suitable to all kinds of power grid.
3.Adapt different requirements: remote control function(RC),
4.Easy maintance: Module desig.
5.Display function of malfuction: Monitor the SPD operation status.
6.Easy installation: Standard size, small dimension.
Model and Meaning
Application (Protection grade B class)
OBV8 series surge protector devices is applicable to AC 50~60Hz, 380V and TT, TN etc. power supply system.
It is also widely used for all kinds of power supply Second class(B class) for over voltage protectio. Generally, it is
installed in low voltage main distribution box or low voltage main switch box of buildings.
