Notes:
• UL recognized component, UL File E153537.
• Model number marking on tube: 26-xxx V.
• The rated discharge current for TRIGARD® Gas Discharge Tubes is the total current equally divided between each line to ground.
• Sparkover limits after life ±25 %, IR >108Ω (-25 %,+30 % for Model 2026-07, 2026-09 and 2026-60).
• Line to Line voltage is approximately 1.8 to 2 times the stated Line to Ground breakdown voltage.
• At delivery AQL 0.65 Level II, DIN ISO 2859
1 Tube meets BT requirement Type 14 A/1 (210-310 V).
2 Network applied.
3 DC Sparkover may exceed ±25 % after discharge, but will continue to protect without venting.
