| Öğe açıklaması | Overvoltage protection / overvoltage protection type 1+2+3 (b+c+d) according to EN 61643-11:2012 / pom i 4 LCF 100KA 280V/25KA is used for protection of mains and appliances against the effects of overvoltage wave caused by a close, direct or indirect lightning hit. Connected TN-s, 3 phase, 5 wire system (L1, L2, L3, n and PE). Designed as one monoblock with VARISTOR and gas filled spark gap connected in series which ensures a complete separation of l-n, n-PE, with zero residual currents. High diverting capability provided by power varistors mov and lightning arrester. Exceptional properties: Zero leaking current (LCF version) and zero follow current. Mounting is on DIN rail TS35 MM. Usage as the 1ST level ( T1, coarse protection) in a 3-LEVEL overvoltage protection concept. It provides overvoltage protection for appliances installed in the main distributor in the range of T1, T2, T3 (co |
