Notes:
• UL Recognized component, UL File E153537
• Surface Mount (SM) parts may show a temporary increase in DCBD after the solder refl 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
