surge protection device

The BP25VT 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 location of high risk exposure or LPZ 0-2 building entrances ( IEC 62305-4) to against the damage from direct or close lightning strikes.

The BP25VT PN50 is class I & class II (or T1+T2 ) prewired two poles SPD designed for low-voltage power system lightning current & surge protection, especially for location of high risk exposure or LPZ 0-2 building entrances ( IEC 62305-4) to against the damage from direct or close lightning strikes.

Photovoltaic system Surge Protection PROSURGE® SPV series employ high energy Metal Oxide Varistor (MOV), and constructed with our patented thermal protection and arc extinguishing technology which ensure safe disconnection while faulty current or abnormal voltage happened.

Photovoltaic system Surge Protection PROSURGE® SPV series employ high energy Metal Oxide Varistor (MOV), and constructed with our patented thermal protection and arc extinguishing technology which ensure safe disconnection while faulty current or abnormal voltage happened. They are recommended for used on the dc-side of the DC-AC inverter, and PROSURGE® SP series on the ac-side to protect AC mains power supplies. The number and location of SPV SPDs on the DC side depend on the length of the cables between the PV array and inverter.

PROSURGE DM-…/M2N4 is UL listed dataline protectors provide surge protection for 1-pair balanced (symmetrical) lines with shielded in the data, signal or communication system, suitable for use in category location B, C (ANSI/IEEE C62.41) or directly at the upstream near the protected devices.

SP Series UL recognized Type 1ca Surge Protection Device or class II SPD per IEC61643-11; For low-voltage power supply system surge protection, especially for point of entry (Category C,D, ANSI/IEEE C62.41) and sub-circuit (Category B, ANSI/IEEE C62.41)protection. Three phase protection, for TT, IT, TN-S, TN-C system; In 20kA, Imax 50kA per pole;
