SPD Type 1+2 - IsoPro Series

Multipole lightning current arrester type 1 + 2 for the use in 1 , 2 and 3 pha-se TNS, TT, TNC, TN and IT systems, for protection of low-voltage consumers’ installations in business and residential areas against surges caused by lightning or switching actions in the network. The arresters can be installed at the transition 0A to 2 accord-ing to the lightning protection zones concept.
