Powerful power SPD

Detailed Product Description

 

This SPD is designed according to the IEC standard. It is applied to any lightning protection grade of the 220v power distribution system.

Characteristics of lightning arrester

(1) Modular design, good leak tightness

(2)Working indication, remote signal interface, deterioration indication

(3) It can be installed on 35mm electrical rail so the installation and wiring is convenient

(4) Applying temperature-controlling circuit breaking technology, overcurrent fuse, thermal circuit breaker, automaticly tripping when deteriorating

(3) Low residual voltage, fast response, high current capacity,long life span

(4) Various specifications, easy maintenance

Applicable scope of lightning arrester

(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
