An optional Switch-Grade Fail-Short device i/ available. The optional Fail-Short a//embly will activate at a temperature of ±ꢂ5 °C – ±ꢂ7 °C
to provide a high conductive path to ground in ca/e of a thermal overload. GDT/ equipped with the optional Fail-Short device /hould be
/oldered either manually at a temperature that i/ below the activation temperature of the Fail-Short mechani/m, or u/ing a /elective /oldering
proce// that doe/ not exceed ±ꢂ2 °C.
Notes:
• UL recognized component, UL File E153537.
• Model number marking on tube: ±6-xxx ꢃ.
• The rated di/charge current for TRIGARD® Ga/ Di/charge Tube/ i/ the total current equally divided between each line to ground.
