1. Fatech Class I+II lightning and surge arresters, is suitable for TT and TN earthing systems. 3P+N construction lightning and surge arresters based on large power metal oxide varistors and assemble a metal oxide varistor and a gas discharge tube in series between phase line and neutral line, with no follow current. 2. Characteristics 1) Surge protective device with special design for saving installation space— width 18mm/pole. 2) High discharge current— Iimp12.5kA per pole. 3) Each pole with one indication window, indication window for clear display of SPD status. 4) Remote controlling function for your option. 5) Pluggable module— convenient for maintenance. 6) Protection mode — L1,L2,L3, N-PE 7) 3 phase, 4 poles. 3.
