Type II Surge Arrester, 3 Phase + Neutral, Remote Contact, 300V 50kA - VPU AC II 3+1 R 300V/50KA

The Weidmüller VPU AC II 3+1 R 300V/50KA is a four-pole surge arrester in a 3+1 arrangement with a remote signalling contact, for the main or sub-distribution board of a 230/400 V installation. The separate N-PE summation arrester makes it the correct choice for TT and IT systems as well as TN-S and TN-C-S, where a 4-pole (4+0) unit would not be permitted.
