The BP25V PN50 is class I & class II (or T1+T2 ) prewired two poles SPD designed for low-voltage power systemlightningcurrent & surge protection, especially for location of high risk exposure or LPZ 0-2 building entrances ( IEC62305-4)toagainst the damage from direct or close lightning strikes. With built in PROSURGE high energy MOV and GDT, BP25V PN50 ensures remarkable lightning current dischargecapacity up to 25 kA 10/350μs(L-N) and 50kA 10/350μs(N-PE). The unique design of thermal protectionprovidesquickthermal response and secure disconnection. BP25V PN50 is ideal protection for environments with frequent switchingoperations or lightning strikes.
