Siemens Building Technology ASK791.165 Fusible Link 318423-701 while reverse wiring protection safeguardsThe Siemens ASK791. 165 is a precision engineered 165F electrical fusible link designed for integration with UL listed fire and smoke control damper actuators. Built specifically for the OpenAir GJD series, this heat responsive device serves as a critical fail safe within commercial HVAC ventilation systems. When ambient duct temperatures exceed the 165F (74C) threshold, the sensor interrupts power to the actuator, allowing the internal spring return
