Product description
IPK BC TNC 350 (/FM) is a 3-pole lightning current surge arrester for the protection of unstable TNC-Power
Net Systems and IPK BC TNS 350 (/FM) is a 4-pole lightning current surge arrester for the protection of
unstable TNC-Power Net Systems with high TOV risk.
These combined devices with a 2-stage protection of class I and class II SPD. It contains in the class I stage a
hermetical sealed heavy-duty isolating spark-gap, filled with inert gas. The class II stage contains a high
performance MOV + GDT in serial connection.It has a selective function and is a redundant execution.
This makes dangerous blow-out vents unnecessary. This also saves you from keeping the safety distance to
adjoining electrical components usually necessary to avoid unwanted electric arcs. There is no risk of leakage
current which could corrode grounding system!
The protective circuit is installed in an easy-to-handle compact housing of only 88mm (5 DIN modules, each
17,5 – 18mm) with fixable snap-on clips for mounting on 35 mm form C DIN rail. Large size screw terminals for
wire connections up to 50mm² for optimal ground connection.
There is optional available a built in potential-free thermal sensor with NC remote signal contact (FM).
Application
The IPK devices for TT net are usually installed in main-distribution panels, at the boundary LPZ 0B-1 or higher,
according to the lightning zones concept of IEC EN 62305:2006-10 part 1-4 (DIN EN 62305:10.2006,Teil 1-4;
VDE 0185-305:2006-10, Teil 1-4)
