Mechanical Fusible Link
– Consists of two strips of metal soldered together with a fusible alloy
– Designed to melt at a specific temperature
– Used in fire sprinkler systems
– Used in mechanical automatic door release mechanisms for fire doors
– Used in fire dampers in ventilation systems
Electrical Fusible Link
– Type of electrical fuse
– Constructed with a short piece of wire
– Wire is typically four AWG sizes smaller than the wire being protected
– Common in high-current automotive applications
– Wire is encased in high-temperature fire-resistant insulation
Fire Sprinkler Systems
– Mechanical fusible links are used as triggering devices
– Fusible links melt at a specific temperature, activating the sprinkler system
– Help control and suppress fires
– Can be found in residential, commercial, and industrial buildings
– Important for fire safety and prevention
Automatic Door Release Mechanisms
– Mechanical fusible links are used to close fire doors
– Fusible links melt at a specific temperature, releasing the doors
– Prevent the spread of fire and smoke
– Commonly found in warehouses and other large buildings
– Enhance fire safety measures
Fire Dampers in Ventilation Systems
– Fusible links are used in fire dampers
– Fusible links melt at a specific temperature, closing the dampers
– Limit the spread of fire and hot gases through a building
– Important for containing fires and protecting occupants
– Found in various types of buildings, including residential and commercial spacesSources: https://en.wikipedia.org/wiki/Fusible_link
