Ruskin FL-165A Fusible Link Els PW 29614 While the SWT3335 is standardThe Ruskin FL 165A Fusible Link is a critical safety component engineered for precision thermal response in HVAC fire dampers and ventilation systems. Designed for industrial and commercial reliability, this 165 degree F fusible link acts as a physical failsafe, melting at its designated temperature to trigger the immediate closure of fire and smoke dampers. This mechanical activation effectively isolates ductwork zones, preventing the migration of
