Description
AC surge protection WPX-MPA160-4203+N surge protective 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 is suitable for being used in TT, TN-S, and low voltage AC distribution system and provides B class surge protection for three phase power supplies. The WPX DIN rail surge protectors make it easy to embed state of the art surge protection into these automated processes and protect these sensitive circuits. The WPX DIN rail surge protection series uses large block MOVs with a patented thermal detection circuit that eliminates the need for separate overcurrent fusing allowing for a smaller footprint where conserving space is very important.
