duct High limit switch Applications
Firestat Duct High Limit Switches provide an added layer of protection for HVAC systems by monitoring for excessive air temperatures in ductwork. These controls use a helix bi-metal sensing element that reacts quickly to sudden temperature rises, triggering a snap-action switch to interrupt the circuit. By automatically shutting down equipment when temperatures exceed a preset threshold, Firestat switches help prevent overheating and potential system failure. Commonly installed in apartment buildings and multi-unit facilities, these controls support compliance with safety standards while protecting both equipment and occupants.
