Description
AC surge protection WPX-MPA120-4203+N surge protection device is for protecting low-voltage consumer’s installations against indirect lightning discharges and is to be installed in LEPM zone: LPZ1 - LPZ2 as per IEC 62305. It consists of three high performance varistors and one GDT type power supply module. It is applied to equipotential bonding of the low voltage distribution boxes in the building, providing protection against the overvoltage arising from the lightning strike to the power supply system of class 2 or faulty operation. Option from standard IEC61643-1 and GB GB18802.
