Notes:
? UL Recognized component, UL File E153537
? Surface Mount (SM) parts may show a temporary increase in DCBD after the solder re?ow process. Most devices will recover
within 24 hours time. It should be noted that there is no quality defect nor change in protection levels during the temporary change
in DCBD.
? Sparkover limits after life ±20 % (-25 %, +30 % for Model 2035-09, 2035-60), IR >10 8 .
? At delivery AQL 0.65 Level II, DIN ISO 2859.
