Product Description

OBV8 class B Lightning Surge Protectors are highly inevitable part of any AC Power Electrical Installations. Lighning surge protectors are designed to protect low-voltage systems against high surge currents and overvoltage in cases triggered by indirect or direct lightning strikes. lightning current arrestors OBV8 meet the type 1 requirement class according to IEC 61643-11. These devices protect low-voltage consumer systems from overvoltages of all types and are available in single-pole to four-pole versions. The voltage-limiting, high-performance spark gaps provide several benefits. A short response time, a low protection level and high current leakage capability with long service life.

Product Features

●Strong protection function: Max current amount 150kA(8/20 s), low remnant voltage, adopt independent information property right and high performance sensitivity resistance components, the expertise inner metal screen protection module, built-in over-current and over-heat, controlled by temperature controlled open circuit technology, can realized Kevin connection.

●Full-scale protection: adopted OBV8 arrested module to be applicable to all kinds of netty.

●Adaptive different requirements: remote control function(RC).

●Easy maintains: Module design, protection investment.

●Display function of malfuction; Standard size, small volume.

Application (Protection grade B class)

OBV8 series surge protector devices is applicable to A.C50~60Hz 380 and below TT TN etc power supply system, wid ely applica ble to all kinds of power supply Second class(B class) over voltage protection, General installed in low voltage main distribution box or low voltage general switch cabinet of building.

Product connection

Large through-flow product is applicable for single phase, three-phase surge protection devices under various power supply systems through different combinations,especially, it is applide for TT system 3+NPE protection adopted by our country power network, widely.
