Group SPD Surge Protective Devices

Group SPD Surge Protective Devices
Product Detailed
Group SPD, which is suiting to A.C 50/60 Hz , 380V and under 380V voltage electric power system 1..       Usage and the Scope of Application Voltage limiting type SPD combined with voltage switching type SPD is formed the Group SPD, which is suiting to A.C 50/60 Hz , 380V and under 380V voltage’s electric power system and protects all the distribution systems shocked by the thunder or surge over voltage. Since the voltage switching SPD is connected between zero line and earth line, at the same time with its much higher maximum continuous operating voltage and enough impulse current capacity, it will have its peculiar superiority when used in TT system.2.       Technical Parameters Table 1
