KNFX380-60三相(xiang)(xiang)電(dian)(dian)(dian)源(yuan)(yuan)防(fang)(fang)雷箱，適用(yong)于(yu)防(fang)(fang)爆(bao)要求下三相(xiang)(xiang)電(dian)(dian)(dian)源(yuan)(yuan)供電(dian)(dian)(dian)系(xi)統(tong)，屬于(yu)電(dian)(dian)(dian)源(yuan)(yuan)保護(hu)的(de)C級防(fang)(fang)護(hu)產品，并聯連接在供電(dian)(dian)(dian)系(xi)統(tong)的(de)電(dian)(dian)(dian)源(yuan)(yuan)線上，防(fang)(fang)止外界雷擊、電(dian)(dian)(dian)磁干(gan)擾或系(xi)統(tong)內部脈沖(chong)電(dian)(dian)(dian)涌(yong)及瞬間過電(dian)(dian)(dian)壓對(dui)供電(dian)(dian)(dian)系(xi)統(tong)設備(bei)的(de)損害；有(you)雷擊記數和遙(yao)信告警功(gong)能，具有(you)放電(dian)(dian)(dian)能力大、防(fang)(fang)護(hu)電(dian)(dian)(dian)平(ping)低(di)、結構合理、安(an)裝方便等特點，能保證對(dui)供電(dian)(dian)(dian)系(xi)統(tong)的(de)防(fang)(fang)護(hu)效果。

本產品利用目前常用的防護元器件開關型器件（其在無電涌及過壓時呈現高阻抗，一旦電涌及過壓達到防護器件的選定值，即呈現低阻抗）和限壓型器件（其在無電涌及過壓時呈現高阻抗，一旦電涌及過壓達到防護器件的選定值，即開始啟動并會隨著電涌及過壓的增加，阻抗會不斷減小）的對電涌及過電壓工作時的非線性特性，加上其快速的響應特性，將電涌及時泄放到大地，并將電壓鉗制在設備能承受的電壓范圍內，保證設備運行。
