NOARK 4P B+C 275V surge arrester
The surge arrester line consists of class 1+2 devices. They serve to protect electrical installations against direct lightning strikes of low intensity. Suitable for lightning protection zone LPL III, IV according to EN 62305 in a 3-phase TN-C network, where the total surge current introduced into the electrical installation is 37.5 kA and its surge may be 75 or 100 kA depending on the configuration and location of the earthing point, the earthing of the lightning protection installation and the place of installation of the surge arrester. The modular design with interchangeable inserts allows quick and simple replacement of the functional modules in case they burn out, due to the frequent occurrence of surge peaks.
