1000V DC 3 Poles 40kA 3P PV Solar Power Surge Protective Device

 

Brief Introduction of Surge Protective Device

 DKG-20 1000V DC 3 Poles 40kA 3P PV Solar Power Surge Protective Device(short for SPD)  is a parallel type module DC power surge protection device. Adopted high temperature and resistant flame retardant plastic shell, it is dedicated to the lightning protection of pv DC power distribution system. With features of good sealing, beautiful appearance, easy installation, dust-proof, anti-corrosion and flame retardant, it can work stably under the harsh environment. This product is used for lightning protection of DC power distribution equipment, such as PV combiner box, PV DC power distribution cabinet and grid tie inverter. The lightning protection mode is Positive-PE, Negative-PE.
