ED 50 secondary protection
|
ED50 surge protections are used mainly for the secondary protection of single- and three-phase networks on the main electrical switchboard.
They provide common-mode protection (between the active conductors and earth) and are available in single-phase and three-phase versions and in a "remote signalling" version (ED50S). The ED50-400 is especially well suited to IT network.
Available in 120V, 230V, 320 and 400V versions.

| Connection area | 4-50mm2 |
