N/A 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. 8 Sparkover limits after life 25 %, IR >10 (-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 (3) Network applied. (4) DC Sparkover may exceed 25 % after discharge, but will continue to protect without venting. *RoHS Directive 2015/863, Mar 31, 2015 and Annex. Specifications are subject to change without notice.
