What is the function of fusible links?

Fusible links are safety devices that serve to prevent the spread of fire by melting at a specific temperature. When exposed to heat, the link melts, allowing a connected mechanism, such as a fire damper or sprinkler, to activate and control the fire's progress. They are commonly used in fire protection systems to enhance safety in buildings and industrial settings. By responding to heat, fusible links help to minimize damage and protect life and property.
