package type: wooden cases and carton
NDC:5kA
Description
DC U1mA voltage is 6.38+0.3kV
Reference current is 1mA
Reference voltage is 6.38kV
Residual voltage is 11.5+0.5kV
Long duration current is 400A
Nominal discharge current is 10kA
Applications:
Used for distribution arresters.
Arresters which used TGE MOV have below advantages:
--With the same referencevoltage, hold more excellent protective characteristics;
--With the same protectionlevel, arrester have higher reference voltage andcontinuous operating voltage. Therefore, arrester could withstandlower electric stress and for safe operation.
