LY26 series single-phase and three-phase lightning protection /lightningprotection box is suitable for B,C,D grade over-voltage protection,mainlyinstalled in household low-voltage distribution box,when the power supply systemshocked by over-voltage or lightning,it'll rrpidly transmit in ns and limit theover-voltage in safe range and protect the electric equipment,simultaneitydischarge the surge into earth.

Suitable for TT,TN Power Supply System

1,Use high quality resistance.
2,Be replaced for the module(Pull out/instyle )when has operating voltage.
3,Inside protection of over-current andauto fuse.
4,Common&different&full protection mode.
5,Low residualvoltage, quickly response,Large discharge capacity.
6,Be provided withlightning-proof module,acoustical-optical alam and signal of remoteswitch.
7,Could be equipped with counter which record be shockedtimes,
8,The panel shows the state ofprotection(Normal,Aging,Invalidation)

lightning protection box

1,When it is installed Must cut offthe power,never do live working pleaseread this manual,open the protection devices box.the power inlet wire inprotection area and grounding wire(PE)is leaded in protection devices box ,it isconnected firmly with multi-strand copper core wire according to symbols,Theprotection devices box is installed the front of protection device and connectedin parallel,it is cose to the protection as possible as,the connection cinductoris short as possible as.
2,The grounding wire of lightning protection devicesbox is connected with the grounding bus bar of accessory or PEwire,all  protectiondevices,protection devices box and other protection devicesmust be connected with equal potential,the grounding wire shall be short andstraight(the best distance is less than0.5m)
3,Because of the stableperformance,the protection devices box is free maintenance buring being,operated,to prevent aging,no effective,it shall be examined regularly,when thefault lamp lights up,user shall check if the midule contacts well,if itcontacted not will,the module shall be changed.
