Type 7P.43 surge arrester, SPD Type 2 for three-phase TN-C systems without Neutral (PEN conductor). Varistor protection + GDT L1, L2, L3 PEN. Replaceable modules. Signaling with remote contact of the varistor status.

Features include:

• Suitable for AC systems/applications for protection against induced and switching overvoltages
• To be installed on the border between zones LPZ 1 and LPZ 2
• 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
• Visual indicator of the varistor status – functional/to be replaced
• Signaling with remote contact of the varistor status. Connector (07P.01) included in the package
• Replaceable modules
• Compliant with EN 61643-11: 2012
• 35 mm rail (EN 60715) mounting, 17.5 mm per pole
