This lightning arrester is designed according to the ICE standard. It is for the lightning protection of power lines at the junction of LPZ0 and LPZ1. It is applied to the lightning protection of 220v power distribution system.
Characteristic
(1) Power working indication, trouble lamp
(2) Applying temperature-controlling circuit breaking technology, overcurrent circuit, thoroughly avoid fire accident.
(3) Low residual voltage, fast response, high current capacity,long life span
(4) Easy installation and maintenance
Applicable scope
(1) General low-voltage power distribution cabinet and distribution board in building
(2) Power distribution cabinet and power distribution board outdoor
(3) Environment which needs lightning discharge record
(4) TT,TN,ITpower supply system
