Ruskin EFL/SP100/165 Flue Switch 320720-756 Using natural gas components onThe Ruskin EFL SP100 165 is a professional grade 165F fuse switch and heat responsive device designed specifically for integration with fire smoke dampers. As a UL Classified component, this electric resettable link functions as a critical safety cutoff, interrupting power to the actuator when ambient temperatures exceed 165F (74C). This allows the damper's spring return mechanism to engage, ensuring positive closure for life safety and fire
