ED 4000 secondary protectionDatasheet |
ED4000 surge protections are used mainly for the secondary protection of three-phase networks on the main electrical switchboard.
They provide common-mode protection (between the active conductors and earth) and are available with or without remote signalling.
One solution for both TN-S and TN-C network.
Stronger version than normal class II (C) tested products and can be installed with out pre-fuse up to 250A!
