AC SPD TRS9/B120

TRS9/B120 Series surge protective device(Abbreviation: SPD) are suitable for AC 50/60Hz, rated voltage up to 380vIT、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/IEC61643-1 standard.

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.
