TGDY55 series surge protective device is used in the AC50/60Hz, 380V and below TTITTN-Sand TN-C-S power supply systems (or communication systems)for surge protection of indirect lightning and direct lightning or other transient overvoltage and overcurrent providing safe and effective electricity safety.
Surge protective device (hereinafter referred to as SPD) has many protection modes such as phase-to-phase phase-to-earth,phase-to-neutral line, and neutral-to-earth combined protection allowing that the back-end equipment of the low-voltage power distribution system and other equipment can be safely, extensively and effectively protected.
Available Standard: IEC 61643.1
