The BP25V 2P is class I & class II (or T1+T2 ) prewired two poles SPD designed for low-voltage power system lightning current & surge protection, especially for locationof highriskexposure 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, BP25V 2P ensures remarkable lightning current discharge capacity up to 25kA 10/350μs. The unique design of thermal protectionprovidesquick thermal response and secure disconnection. B25V 2P is ideal protection for environments with frequent switching operations 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, sothat 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.
