YCS7 Surge Protection Device

  • General
    YCS7 series Surge Protection Device serves as a voltage-limiting device for the indoor electric power . The product is suitable for the power supply system such as TT、 IT、 TN-S、 TN-C、 TN-C-S, of which frequence is AC 50/60Hz, rated voltage below 230/400V . This type is applied to protect low voltage grid and most kinds of electrical equipments as well as the controlling system. The transient over-voltage in the equipment can be restrained by the Surge Protection Device so that the discharging surge would not rise. Standard:GB18802.1、GB18802.12、IEC61643-1、 IEC61643-21、UL1449 ed.
