Ruskin FL-212A Fuseable Link 340155-7026 it features a pressure-sensitive interrupterThe Ruskin FL 212A fusible link is a 212F thermal response device engineered for high heat industrial and commercial ventilation environments. Designed for UL Classified safety, this component is essential for fire damper maintenance and replacement in fire rated systems. When the ambient temperature reaches its critical 212F (100C) melting point, the eutectic alloy breaks, triggering the fire damper closure via spring return to prevent the passage of
