The G35P is class I & class II combined (or B+C) and designed for low-voltage power system lightning current &surgeprotection, especially for location of high risk exposure or LPZ 0-2 building entrances ( IEC 62305-4) to against thedamagefrom direct or close lightning strikes. With built in PROSURGE Encapsulated TSG (Trigger Spark-Gap) technology, G35P ensures remarkable lightningcurrentdischarge capacity up to 35 kA 10/350 and follow current limiting &extinguishing.
