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 >10 8 Ω (-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
