Notes:
• UL recognized component, UL File E153537.
• Model number marking on tube: 27-xxxV.
• Sparkover limits ±20 % after life, IR >108 Ω (-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.
