An optional Switch-Grade Fail-Short device is available. 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:
• 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 >108
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

Network applied.
DC Sparkover may exceed ±25 % after discharge, but will continue to protect without venting.
