Siemens 9EP3323 Metal Oxide Surge Arrester from China
This metal oxide varistor (MOV) based surge arrester is designed for high-voltage overhead power transmission lines exceeding 1,000V. It protects transformers and switchgear from lightning-induced overvoltages by clamping surge voltages. Classified under 8535.40.00.00 as it functions specifically as a lightning arrester for high-voltage applications.

Import Tips
• Verify arrester voltage rating exceeds 1,000V with test certificates to confirm HTS 8535.40 classification
• Include manufacturer specs showing MOV technology and energy absorption capacity (kJ/kV)
• Avoid misclassification as low-voltage suppressors; provide proof of high-voltage design to prevent reclassification
