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 >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
## (2) Network applied.
(3) DC Sparkover may exceed ±25 % after discharge, but will continue to protect without venting.
*RoHS Directive 2002/95/EC Jan. 27, 2003 including annex and RoHS Recast 2011/65/EU June 8, 2011. Specifications are subject to change without notice.
