How Do Fusible Links Work?

Fusible links use a simple thermal mechanism to activate fire protection systems automatically when exposed to heat.

Thermal Activation

The fusible alloy melts at a defined temperature, releasing the link.

Mechanical Release

Once released, springs or gravity trigger the connected safety device.

Common Applications

  • Fire dampers
  • Fire doors
  • Suppression systems
