Product Description
Key words : Surge Arrester,Surge Protector,Surge Arrester(with NPE) Class C,Surge Protective Device.
Product introduce and application:

- DGM-type surge protector(hereinafter referred to as SPD)adapted to AC,mainly used for rated voltage not exceeding 1000V(RMS),200/380V,50/60Hz power supply system,not exceeding 1500V DC voltage of the circuit and equipment of the Surge Protection.SPD has a phase to phase(L-L),phase to ground(L-NE),phase to neutral(L-N),neutral to ground(N-PE) and combinations such as protected model.
- DGM-based high quality surge protector to use non-linear components and low residual voltage,small discharge current,modulus,and using safely and reliablely,designed and manufactured in accordance with the standards GB18802.1-2002/IEC61643.1,products have passed CE Certification and the national test Room:Beijing Lightning Experimental Device Type Detection Centers.
The DGM2-C20/1+1 exact technology parameter is as below:
Type No. | Rated Voltage(V) Un | Continuous Voltage Uc(V~) | Standard Discharge Current In(KA) | Max Discharge Current Imax(KA) | Protection Level(KA~) | Response Time(ns) |
DGM1(2)-C20 | 220/380 | 275/320 385/420 | 20 | 40 | 1.8 | ≤25 |
DGM-N-PE | 220/380 | 250/255 | 40/60 | 60/80 | 1.2 | ≤100 |
