Product description:<br />
This combined two-pole SPD type PP BCD TN 25/50/LED-350 and PP BCD TN 25/50/LED/FM-350, with remote<br />
signal contacts as well as LED monitoring, offers a complete solution for the protection of single phase TN-Power<br />
Net Systems. They are usually installed in main- or sub-distribution panels or close to equipments to be<br />
protected.<br />
Thanks to the use of the patented, hermetically sealed inert-gas-filled isolating spark-gaps, this SPD allows to<br />
achieve a very high-level discharge capacity without needing blow-out vents. This saves you from keeping the<br />
safety distance to adjoining electrical components usually necessary to avoid electric arcs and fire hazardous.<br />
As there is no risk of leakage currents, this SPD can also be installed before the electric power meter (acc. to<br />
TAB2000, installation rules of the German Union of Electric Energy Suppliers).<br />
This 2-pole SPD is capable to discharge lightning current surges of 25 kA (10/350µs) per phase and totally 50 kA<br />
(10/350µs) to PE.<br />
It self-extinguishes main supply follow-on currents up to 4 kA, so that even small fuses (>35A) will not trip.<br />
Each protective spark gap is installed in an easy-to-handle compact DIN size housing with 2 fixable snap-on clips<br />
for 35 mm DIN rail mounting on each SPD-module. Multifunctional large dimensioned screw terminals for wireand<br />
bus-bar connections. Line installation can be carried out either by parallel wiring via the multifunctional screw<br />
connection terminal L, N, or by serial V-wiring via the terminals L,N to L’,N´ connected with the two-pole busbars.<br />
Optional a sealed potential-free remote signal sensor (/FM) with thermal NC safety function can be built-in. The<br />
wire connection is made via a pluggable screw terminal block.<br />
