UL 1449 Recognized, File E335803 — how to verify our certification and exactly which series and voltages it covers.
| Certification wording | UL 1449 Recognized, File E335803 |
| Standards | UL 1449; CSA C22.2 No. 269.5-17 (Type 5 component recognition) |
| Certificate holder | GUIYANG YIGE HI-TEC ELECTRONIC CO LTD |
| UL Product iQ category | VZCA2 (United States), VZCA8 (Canada) |
How to verify: go to UL Product iQ (productiq.ulprospector.com) and search file number E335803. The record is public and lists every covered model.
Note: our MOVs are UL Recognized components, intended to be built into end products such as SPDs — they are not "UL Listed" end products, and we do not describe them that way.
Voltages are varistor voltages. The three-digit model code reads as the first two digits plus the number of zeros in the third digit (431 = 430 V; 122 = 1,200 V).
| Series | UL 1449 coverage (File E335803) |
|---|---|
| 34S | 31 model grades, varistor voltages 82–1,800 V (codes 820 and 101–182); 430–680 V grades rated Imax up to 50 kA |
| 22S | 22 model grades, varistor voltages 100–820 V (codes 101–821) |
| 20S | 22 model grades, varistor voltages 100–820 V (codes 101–821) |
| 27L | 22 model grades, varistor voltages 100–820 V (codes 101–821) |
| 30S | 620 V, 680 V, 820 V, 1,100 V, 1,200 V only (codes 621, 681, 821, 112, 122) |
| 25D / 30D / 32D / 40D / 44L / 48L / 54L | Not UL covered |
