Notes:

• UL recognized component, UL File E153537.

• Model number marking on tube: 27-xxxV.

• Sparkover limits ±20 % after life, IR >10

(-25 %, +30 % for Models 2027-07, 2027–09 and 2027–60).

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

Network applied.

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