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 21ꢀ °C.

The Rated Impulse Discharge Current for TRIGARD Gas Discharge Tubes is the total current equally divided between each line  
to ground.
