The BP25V 3PN100 is class I & class II (or T1+T2 ) prewired four poles SPD designed for low-voltage power system lightning current & surge protection, especially for locationofhighrisk exposure or LPZ 0-2 building entrances ( IEC 62305-4) to against the damage from direct or close lightning strikes. With built in PROSURGE high energy MOV and GDT, BP25V 3PN100 ensures remarkable lightning current discharge capacity up to 25kA 10/350μs (L-N) and 100kA10/350μs(N-PE).The unique design of thermal protection provides quick thermal response and secure disconnection. B25V 3PN100 is ideal protection for environments with frequent switchingoperations or lightning strikes. A notable feature of BP25V is dual module redundancy design, two individual MOV protection modules in parallel in one pole SPD with two indication windows, so that theSPDcouldkeep on working in spite of one protection module fault or one indication window turns to red. That will help to realize the uninterrupted surge protection, since user canreplacethefailure models according to the timing and the condition
