Other maxi continuous operating voltage can be customized
1.To be mounted between LPZOB or LPZ1 zone and LPZ2 zone, adopts 35mm standard mounting rail . The cross sectional area of multi-strand soft copper conductor:2.50~35mm2.
2.Every phase of SPD shall be protected by fuse or mini circuit breaker from short circuit when SPD is broken down caused by suging voltage.
3.It is mounted in distribution boxes of different floors, computer center, telecommunication room , control room of elevator, CATV room, fire fighting center, distribution box of villa and etc.
1>.SPD as only one side of terminals , able to prevent from being electric touching , indoor fixedly mounted , limiting voltage.
2>.SPD hase built-in disconnector , when SPD is invalid due to overheating or breakdown, the disconnector can automatically separate SPD from the network, meanwhie send an indication signal. The visible window show white color in normal service, if to be separated from network, it will show red color.
3>.1P+NPE, 2P+N,3P+N. SPD consiste of 1P,2P,3P,4P and NPE neutral and earthing protection modules, used in the power supply system of TT, TN-S and etc.
Scope of Application
Power Surge Protector is used for earthing system of power plant ,transformer station ,tower ,communication station ,airport, railway, subway station , high building ,computer room ,oil reservoir in the environmental of moist ,saline and alkaline ,acid and chemical corrosion medium environmental.
