ME-MD-25 series SPD comply to IEC61643, apply to the low voltage power system with 48-60Hz frequency,is a voltage limiting type SPD.It has low outputing residual votlage and quick responding,especially without subsequent currents after lightning electromagnetic surge going trough. Meanwhile, the built-in failure tripping device will trip it off from the main power system when it has any overheatings,overcurrents,or failure to protect the main power system. The main application is to provide protection for sensitive electronic devices,as the L3 power circuit surge protector,wich are mainly installed in the tiered distribution box located junction part of LPZ2 and LPZ3.
