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 2 3 Tube meets BT requirement Type 14 A/1 (210-310 V). Network applied. DC Sparkover may exceed ±25 % after discharge, but will continue to protect without venting. *RoHS Directive 2002/95/EC Jan 27, 2003 including Annex.
