Would it be possible to install a TNS SPD on a TN-C-S network?
Please note that the SPDs with the A9L prefix, which are compatible with TT and TNS, are also compatible with TNS part of TN-C-S networks.
In a TN-C-S network, the neutral conductor N and the protective conductor PE are combined (PEN) up to a certain point, then separated (separation of the neutral conductor N and the protective conductor PE). The A9L SPDs for TNS are therefore compatible with this type of network on the TNS part of the TN-C-S network.
For the TNC part of the TN-C-S network, a 3P surge protector compatible with TNC is required.
