| Description de l'article | Exchange protection module / exchange protection module n-PE for po i type 1+2+3 (b+c+d) according to EN 61643-11:2012 / po i 0 n-PE 260V/12, 5KA - exchange GDT protection module. Usage as the 1ST level T1 of overvoltage protection it provides overvoltage protection for appliances installed in the main distributor in the range of T1, T2, T3 (coarse, medium and fine protection).po i 0 n-PE 260V/12, 5KA - exchange GDT protection module. It is intended to protection of mains and appliances in industrial buildings, administration buildings, buildings of civil amenities and detached houses against the effects of overvoltage wave caused by a close, direct or indirect lightning hit . It decreases overvoltage and restricts overvoltage wave energy. Voltage protection level T1, T2, T3 up ≤ 1, 5 KV impulse current (10/350) IIMP 25 KA max. discharge current (8/20) imax 40 KA nominal discharge curren |
