电源SPD主要安装在配电房、配电柜、交流配电屏、开关箱和其它重要设备、容易遭受雷击设备的电源进线处，以保护设备免遭沿电源线路侵入的雷击过电压造成的损害；可广泛应用于通信、民航、交通、金融、证券、铁路、电力等系统的主电源防护。HD100B4二级（C级）三相电源防雷器，安装于各类380V用电机房配电箱处或UPS前端，保护机房整套用电设备的安全，避免雷电波入侵，击毁用电设备。最大防雷能力为：100KA（8／20），响应时间小于25NS，具有漏电流极小，残压低的优质特点。在同类产品为优质防雷产品.100电涌保护器(以下简称“保护器”)适用于交流50/60Hz，400V及以下的TN-S、TN-C、TN-C-S、TT、IT等供电系统，对电网因雷击或浪涌过电压进行保护。

100KA AC power lightning arrester price, 100KA three-phase AC power surge arrester manufacturers quote, 100KA three-phase AC power surge arrester how much money? 100KA three phase AC power surge arrester. Power supply SPD is mainly installed in power distribution room, power distribution cabinet, alternating current distribution panel, switch box, and other important equipment, vulnerable to lightning equipment power into the line at, to protect the equipment from along the power line invasion of lightning overvoltage caused by damage; can be widely used in communications, civil aviation, transportation, finance, securities, electric power, railway, etc. system for protecting the main power supply. HD100B4 secondary (grade C) three-phase power lightning protector, installation in all kinds of 380V motor housing distribution box office or UPS front to protect room set of electrical equipment safety, avoid the lightning wave invasion, destruction of electrical equipment. Maximum lightning protection capacity is: 100KA (8 / 20), the response time is less than 25NS, with leakage flow is small, the quality characteristics of residual low. In similar products for high-quality lightning protection products of.100 surge protective device (hereinafter referred to as the "protector") applicable to AC 50Hz, 400V and following TN-S, TN-C, TN-C-S, TT, it power supply system, on the grid due to lightning or surge overvoltage protection.

失效脱离装置
保护器的模块上设有失效脱离装置，当保护器因过热，击穿失效时，失效脱离装置自动的将其从电网上脱离，同时给出指款信号。保护器正常时标牌显示绿色，失效脱离后标牌显示红色。

安装注意事项：
● 安装前必须切断电源，严禁带电操作。
● 建议在防雷模块前端串联熔断器或自动断路器。
● 安装时请根据安装示意图所示连接，其中L1、L2、L3为相线，N为零线，PE为地线，切勿错接。安装完成后，合上自动断路器（熔断器）开关，检查工作状态是否正常。
● 安装完毕后将模块插到位，检查防雷模块是否正常工作。brsj17751331240
