Introduction
TPS D20 is dedicated for suppressing the surge from low-voltage electrical device. It’s a surge protective device with the function of modular combinations, which can protect the electrical devices and equipment (such as the EDP system, communication system) installed in its downstream from the surge hazard caused by switch action, electrostatic discharge, induction or direct lightning strike. The maximum discharge current can reach 20KA.So it can be used in the third-level protection for terminal equipment.
Parameters
Rated voltage:230~50Hz
The max operating voltage:255V/50Hz
?Nominal discharge current:10kA
Max discharge current:20kA
Voltage protection grade:≤1.0kV
Application and maintenance
TPS D20 is a Class III (D) overvoltage protector for lightning area of LPZ 2-3 or higher interface, and is commonly used in exquisite over-voltage protection for electronic equipment, to prevent overvoltage interference with terminal equipment. One or two kinds of modules can constitute 2P、3P、4P、1P+N、3P+N combinations, which can provide the transient overvoltage protection for the TT、IT、TN－S、TN－C and TN－C－S system.
