Type 7P.04, surge arresters, SPD Type 1 + 2, for TT systems
and TN-S three-phase with neutral.
Varistor protection + GDT L1, L2, L3-N + spark gap protection N-PE.
Combination of varistor and gas spark gap + 1 gas spark gap, with signaling with remote contact of the state of the varistor and the presence of the GDT (N-PE). Equipped with “Upside down mount” technology.
Replaceable modules.

Features include:

• SPD suitable for low voltage systems for protection against overvoltages caused by direct discharges, induced and operating overvoltages
• To be installed on the border between zones LPZ 0 and LPZ 1
• Combination of high-performance varistors and gas spark gaps (GDT) which ensure:
  • high discharge currents
  • high insulation resistance which eliminates the leakage current
  • absence of subsequent follow-on current
• Extremely low residual voltage
• Replaceable modules
• “Upside down mount” technology (thanks to the double marking of the terminals and the new restraint system of the replaceable module that allows its reversal)
• Visual indicator of the varistor status: functional/to be replaced
• Double screw terminal
• Signaling with remote contact of the varistor status: presence, functioning, to be replaced
• Connector (07P.01) included in the package
• In accordance with EN 61 643-11
• Assembly on 35 mm rail (EN 60715), 36 mm per pole
