Surge protector TNR-X series suitable for low voltage distribution cabinet, main box (cabinet JP), the T1 class provides protection for various electrical and electronic equipment vulnerable to lightning overvoltage of the buildings, for the main distribution system, installed in the main power system of power cabinet intact, as the first grade protection.
The national standard GB5007-2010 4.2 4.8 stipulates that the surge protector of the I type test should be installed in the general distribution box of the power supply. The voltage protection level of surge protector should be less than or equal to 2.5kA. When the impulse current value of each protection mode is not determined, the 10/350us impulse current should be equal to or greater than 12.5kA.
1. The high effective pressure sensitive resistance nanocrystalline graphite material has fast response time.
2. It is suitable for the T1 protection of the main distribution cabinet and JP cabinet in the low voltage distribution system.
3. with remote signal alarm contact, remote monitoring protector installed state;
4. the impact flow rate is large and the residual pressure is low.
5. the standard 35mm rail installation;
6. The installation is convenient and the maintenance is simple.
