Combination arrestor, protection set for TT, TN and IT system

· 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 nonlinear components and low residual 

voltage,small discharge current,modulus,and using safely and reliablely,designed and 

manufactured in accordance with the standards GB18802.12002/IEC61643.1,products

 have passed CE Certification and the national test Room:Beijing Lightning Experimental 

Device Type Detection Center
