The optional Fail-Short assembly will activate at a temperature of 215 °C – 217 °C to provide a high conductive path to ground in case of a thermal overload. GDTs equipped with the optional Fail-Short device should be soldered either manually at a temperature that is below the activation temperature of the Fail-Short mechanism, or using a selective soldering process that does not exceed 210 °C. 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 (2) Tube meets BT requirement Type 14 A/1 (210-310 V). (3) Network applied. DC Sparkover may exceed ±25 % after discharge, but will continue to protect without venting.
