TNR-X series surge protective device is
suitable for protecting all kinds of electronic and electrical equipments in
buildings of T1 class lightning protection area, where it’s easy caused lightning
overvoltages. Mainly used for main distribution system and installed on the
front end of power distribution cabinet as First tier protection
IEC61643-11 Standards
A surge protective device of T1 should be installed at the general distribution
box connected with the power supply. The voltage level of surge protective device
should be less than or equal to 2.5KV. When the impulse current value is not
determined, the impulse current should be equal to or larger than 12.5KA
