Surge Lab Korea, has been developing new surge protective devices since 1997.
In 2008, we finally invented new surge protective device named a GCA(Gate Control Arrestor) which is patented in Korea and the quality is the world best. This make it possible for SPD's let-through voltage of 6kV to come out under 50V. This is a supprising quality.

1. Patented technology (GCA device loaded, under voltage tracking technology solitary development application)
2. The lowest Let-Through Voltage : Super(under 50V)/PRO(under 420V), measurer-50V IEEE C61.41(4&＃13240;/1.2~50&＃13234;, 2kA/8~20&＃13234;) 2
3. Various installation method : able to organize in standard 50AF Frame, DIN-Rail method, block module compound method
4. All products equipped according to capacity :  10&＃13188; ~400 &＃13188;
5. All products international certification (CE), UL1449, IEEE C62.41 standardized goods
6. All products epoxy-molded for improvement of resistance of heat, water and dust
7. Quick motion speed : 1pico-second , motion indication skill - LED
8. Applied Transient Source : Lightning, Surge, Impulse, Oscillatory, Ring-wave
