Elsie Manufacturing B165-LONG HOOK Fusible Link W/Long Hook 1.5" L 0.563" W 165°F

The Elsie Manufacturing B165-LONG HOOK Fusible Link W/Long Hook is a heat-responsive safety component that releases its connection when exposed to its rated temperature. The 1.5-inch length, 0.563-inch width, long hook, and 165248F rating determine its mechanical configuration and thermal release point. It attaches to the designated fusible-link assembly remaining secured until excessive heat causes the fusible section to separate in HVAC systems. This action allows the connected mechanism to move into its protective position, limiting continued operation during elevated temperatures and providing an automatic response when the surrounding area reaches the rated threshold.
