Ruskin a-212 Fuse Link Fire Damper

Product Description

The RUSKIN a-212 is a replacement fuse link designed for use with fire dampers in commercial and residential HVAC duct systems. Fuse links are the thermal-release components that hold a fire damper blade in the open position during normal operation. When ambient temperature rises to the rated threshold during a fire event, the fuse link melts and allows the damper to close, restricting airflow and limiting fire and smoke spread through ductwork. The a-212 is a direct-replacement part intended for installation by licensed HVAC or sheet metal technicians performing fire damper maintenance or code-required inspection and resetting service.

The RUSKIN a-212 fuse link is compatible with Ruskin IBD2, IBD20, FDR25, CFD, and CFDR series fire dampers. These dampers are commonly installed in HVAC duct systems at rated fire wall and floor penetrations in commercial buildings and multifamily residential construction. Replacement of fuse links is a standard part of periodic fire damper inspection per NFPA 80 and local authority having jurisdiction requirements.
