Favorable power surge arrester

Detailed Product Description

This surge arrester is applicable to lightning surge protection of the power lines of lightning region at the junction of LPZ1 or LPZ2 areas and  LPZ3 district.

(1) Especially suitable for the second-class protection of lightning protection level for B-class electronic information system, installed in the calculation of machine room UPS power supply input;

(2) The achievement of B + C-level function, a lower residual pressure;

(3) The anti-radar part modulation, two levels of linkages, series installation, maintains simply;

(4) The use of "1 +1" circuit structure, can be applied to different power supply system to avoid the fire occurred;

(5) Dust-proof, anti-corrosion, explosion-proof, fire-retardant features;

(6) Has the automatic control separation, lightning counter, operation  indication, remote signal interface and deterioration alarm indication functional, green (normal), red (failure);
