The Meaning Of Surge Protector Level 1, Level 2, Level 3, Bcd Level, Level T1 Level And Level T2 Level

1. Level 1 power lightning arrester, according to national standards, refers to surge protectors for T1 test (AM-10/350, AM-L/N-BD series belong to level 1 surge protectors)
2. Level 2 power lightning arrester, according to national standards, refers to surge protectors for T2 test ≥40kA (AM40, AM60, AM80 series belong to level 2 surge protectors)
3. Level 3 power lightning arrester, generally refers to 20kA surge protectors (AM20 series belong to level 3 power lightning arresters)
4. Class B surge protectors, including surge protectors for T1 test and surge protectors for T2 test 60kA and above
(AM-10/350, AM60, AM80, AM100, AM120, AM160 series are all Class B surge protectors)
5. Class C surge protectors refer to surge protectors with a maximum flow rate of 40kA in the T2 test (AM40 series)
6. Class D surge protectors refer to surge protectors with a maximum flow rate of 20kA in the T2 test (AM20 series)
7. Class T1 refers to the T1 test level, the test waveform is 10/350μs, and the main parameters are marked with impulse current Iimp.
Class T2 refers to the T2 test level, the test waveform is 8/20μs, and the parameters are marked with maximum discharge current Imax and nominal discharge current In.
