Type 7P.02 surge arresters, SPD Type 1 + 2, for TT systems and TN-S single phase with Neutral. Varistor protection + GDT between L-N, and GDT between N-PE. Combination of varistor and gas spark gap, with visual signaling and with remote contact of the status of the varistor/GDT and of 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 and 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
• 35 mm rail (EN 60715) mounting, 36 mm per pole
