Surge protection

<p>Type 7P.42 surge arrester, SPD Type 2 for single-phase TT and TN-S systems with Neutral. Varistor protection + GDT between L-N, and GDT between N-PE. Replaceable modules. Signaling with remote contact of the varistor status.</p>
<p>Features include:</p>
<ul>
<li>Suitable for AC systems/applications for protection against induced and switching overvoltages</li>
<li>To be installed on the border between zones LPZ 1 and LPZ 2</li>
<li>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</li>
<li>Extremely low residual voltage</li>
<li>Visual indicator of the varistor status – functional/to be replaced</li>
<li>Signaling with remote contact of the varistor status. Connector (07P.01) included in the package</li>
<li>Replaceable modules</li>
<li>Compliant with EN 61643-11: 2012</li>
<li>35 mm rail (EN 60715) mounting, 17.5 mm per pole</li>
