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: (2) Network applied. (3) The Rated Impulse Discharge Current for TRIGARD® Gas Discharge Tubes is the total current equally divided between each line to ground. • At delivery AQL 0.65 Level II, DIN ISO 2859.
