Product Content Description:

Scope of Application
TXSPD Surge Protection Device (TXU3, surge protective device) with B, C, D series large current modular. TXSPD is used for power supply systems of AC 50/60Hz, the TT, IT, TN-S, TN-C, TN-C-S of rated voltage 380V and below, ro protect the power grid caused by lightning or surge overvoltage. The design is based on the C61643-1,GB18802-2002, it can discharge the 100kA lightning current, case is installed on 35mm electric rail, the detachment device automatically will be out of its power grid, meanwhile the status indicator turns from green to red. TXSPD Surge Protection Device has protection modes of common mode (MC) and differential mode (MD).
TXSPD complies with the requirements of GB18802.1 and IEC61643-1 standard.
