TUV Certified Iimp 25kA Three phase VT Surge Arrester

With built in PROSURGE VT technology, BP25VT ensures remarkable lightning current discharge capacity up to 25kA 10/350μs and No leakage current & No follow current. It can be applied in most electrical installation and provide better reliability and safety protection, and particularly suitable for system with permanent insulation monitoring.

A notable feature of BP25VT is dual module redundancy design, two individual MOV protection modules in parallel in one pole SPD with two indication windows, so that the SPD could keep 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 can replace the failure models according to the timing and the condition.

lTUV certified T1+ T2 SPD per IEC/EN 61643-11 standard

lPrewired four poles SPD (“3+1” circuit) for use in three phase TN/TT systems

lUnique thermal disconnector design provides quick thermal response and secure disconnection

lDual module redundancy for one pole SPD and dual fault indication windows, with optional remote signal contact.

lLightning current capacity up to 25kA 10/350μs (L-N), 100kA 10/350μs (N-PE); Surge current capability up to 100kA 8/20μs (L-N), 150kA 8/20μs (N-PE)

lLow voltage protection level due to VT tech. 

lHigh short-circuit current rating up to 50kArms, suitable for application in most AC power system.

lLong service life because of no leakage current and follow current

lBetter reliability and robustness, Higher TOV (Temporary Over-Voltage) withstanding performance

lPluggable module for easy replacement without the need to remove system wiring.

lComply with UL1449 5^th, IEEE C62.41,CSA C22.2 standards
