Q: What does this do
A: It is as fusible link: from Wikipedia: A mechanical fusible link is a device consisting of two strips of metal soldered together with a fusible alloy that is designed to melt at a specific temperature, thus allowing the two pieces to separate. Mechanical fusible links are utilized as the triggering device in fire sprinkler systems and mechanical automatic door release mechanisms that close fire doors in warehouses, etc. Some high-security safes also utilize fusible link-based relockers as a defense against torches and heat-producing tools. Mechanical fusible links come in a variety of designs and different temperature ratings.
Q: I'm asking because I turned on my heat at the house and it came out of my vent
A: humm - Im not an HVAC guy - but it a loose fusble link came out of your vent - I would have to say that is not a "good thing". Fusible links, in my business anyway, are used in fire suppression and life safety applications. I would be concerned and call an HVAC service company immediately.
