Surge protection

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:
<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>
</ul>

7P Series - Surge Protection Devices (SPD)

1.000 V DC Max (or N+PE connection for spark gap modules)

275 V Max for SPD Type 1 “Low Up”, Type 2 (Uc) (for UN = 230-240 V AC) and Type 3

260 V Max (U ) for SPD Type 1+ 2 (for U = 230-240 V AC)

255 V Max (U ) for SPD Type 1, N+PE (7P.09)

Built-in remote status signalling contact

Finder’s 7P series of Surge protection devices (SPD’s) are a great addition to any control panel or distribution board, especially with the introduction of the new 18th edition wiring regulations.
