low voltage surge arrester

Detailed Product Description

 

This surge arrester is designed according to the IEC 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 380v power distribution system.

Characteristic

(1)   Power working indication, trouble lamp and lightning counter

(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
