| Protection indication | Green: OK; red: replace |
Selection & installation notes
- The capacity column does not identify In, Imax or the test waveform. Do not infer a tested surge rating solely from the model number.
- The photographed VU1-40 ratings illustrate one unit and do not apply to all pole counts or capacity variants. Confirm the exact order-code datasheet.
- Confirm system earthing, continuous operating voltage Uc, protection level Up, discharge waveform, backup protection and short-circuit coordination before selection.
- The source does not provide verified dimensions, wire range, torque, environmental ratings or certification documents for each S-series model. Request these with the quotation.
- The generic naming graphic includes T1 and DC options, while this page is for AC T2 products. Do not assume a T2 unit is suitable for a T1 or DC application.
Based on the official Chinese product page and selection charts ↗. Checked 2026-09-15. Confirm the current specification for the exact model when ordering.
