1. FATECH Class II surge arresters have large discharge current value, high operating voltage, suitable for TN-C, TN-S, TT and IT grounding systems. The cartridges are pluggable design, could be changed easily. These surge arresters not only with visual inspection window, but also can remote transmit “cartridge needs change”information to the technician. 2. Characteristics 1) Narrow size surge protection device special design for saving installation space—width 9mm/pole 2) High discharge current— Imax 40kA per pole. 3) Indication window for clear display of SPD status— each pole with one indication window. 4) Remote controlling function -for your option. 5) Pluggable module— convenient for maintenance. 6) Protection mode — L1, L2, L3-N, N-PE 7) 3 phase, 4 poles 3.
