ProductDescription:
LY26 series single-phase and three-phaselightning-proof box is usitable for B,C,D grade over-voltage protection,mainlyinstalled in household low-voltage distribution box, when the power supplysystem shocked by over-voltage or lightning, or lightnin, it'll ripidly transmitin and limit the over-voltage in safe range and protect the electricequipment,simultaneity discharge the surge into earth.
Suitable for TT,TN power supplysystem:
1. Use high quality resistance,
2.Be replaced for the module when has operatingvoltage.
3.Inside protection of over-current and autofuse.
4.Common&different&full protectionmode.
5.Low residual voltage,quikcly response,largedischarge capacity.
6. Be provided with lightning-proofmodule,acoustical-optical alarm and signal of remote switch.
7.Could be equipped with counter which recordbe shocked times.
