Description
The Trane FUS01348 Fuse Link is a thermal cutoff component used to interrupt electrical continuity when the surrounding temperature reaches 128C. It contains a heat-sensitive element that opens the circuit once its activation point is exceeded stopping current flow to connected component. In HVAC systems, it is installed in high-temperature section such as furnace heat exchangers or air handler safety circuits where it act as a final layer of protection against overheating. It helps isolate electrical power during abnormal thermal conditions, reducing the damage to surrounding components and ensuring controlled shutdown of the system.
