ABB 2CCF606000R0001 OVR404 4L 40-275 P Surge arrester 20 kA Piece 1 pc(s)

Surge Arresters TYPE 2 of the OVR404 series are suitable for protecting electrical low-voltage systems and terminal equipment in the 230/400 V system. The devices can be used for the application as surge suppressor according to VDE 0100 part 443 and part 534 as well as within the framework of the lightning protection zone concept at the zone transition between 0B and 1 and higher. The high nominal leakage current of 20 kA makes possible an increased life compared with the minimum requirements of the standard. The devices consist of a base unit and pluggable protection modules, which can be removed very easily for performing the insulation measurement. The contacts are made directly via the Smissline TP socket system. The surge arresters are tested as type 2 conductors according to test standard DIN EN 61643-11 (VDE 0675 part 6-11) and class II according to IEC 61643-11.
