Trane FUS0823 Fuse Link If the circuit is openThe Trane FUS0823 Fuse Link is a critical safety component designed for precise thermal protection in commercial and residential HVAC systems. Engineered as an open surface mount fuse link, this device is calibrated to trigger at a 208F opening temperature. When the surrounding environment or equipment surface exceeds this threshold, the internal link interrupts the electrical circuit to protect high value components from thermal damage. As a veteran
