TRS5 7KA/3P surge protective device(Abbreviation: SPD) belongs to Type1 and Type2 (8/20 and 10/350 waveform) lightning protection, used in AC 50/60Hz, rated voltage up to 275vIT、TT、TN-C、TN-S、TN-C-S and other power supply system，It protects the system from indirect and direct lightning effect or other transient over voltage. SPD is designed by according with GB 18802.1/1EC61643-1 standard.

SPDs according to IEC/EN standards

Lightning protection module plug design, Lightning protection module can be replaced, simple installation, convenient maintenance

SPD for Power Systems

Safety lock design, easy to pull out and replace Can be equipped with remote signaling function Easy to install and maintain

Instantaneous lightning protection

When the system lightning transient overvoltage, surge over-voltage protector conduction immediately fall into the earth, and thus protect the electrical equipment.
