## Notes: 

## **• UL recognized component, UL File E153537.** 

- Model number marking on tube: 27-xxxV. 

- Sparkover limits ±20 % after life, IR >10[8] Ω (-25 %, +30 % for Models 2027-07, 2027–09 and 2027–60). 

- At delivery AQL 0.65 Level II, DIN ISO 2859. 

## (2) Network applied. 

- (3) DC Sparkover may exceed ±20 % after discharge, but will continue to protect without venting.
