LOW VOLTAGE

Typical use: in TN-C, TN-S, TT and IT with direct connection to the ground (A and B) and 1 + 1 or 3 +1 (C) according to IEC 60364-5-534. They are generally installed in in Main Distributions Boards (MDB) or at the origin of low voltage systems, as well as in Sub Paintings SQBT.

Features:

  • They are marked by a power interruption that in case of failure of the SPD is able to extinguish independently the follow current network. They not therefore need a fuse back-up/support.
  • They have a progressive indicator performance. Therefore they simplify the maintenance, facilitating the choice to replace during planned interventions.
  • They are marked by Pollution Degree 3 which makes them suitable for installation in polluted environments (electrically conductive) found in dusty or conductive fumes.
