Description
The Ruskin EFL/SP100/165 is a 165°F-rated fuse switch designed as a spare part for Ruskin’s EFL series damper actuator and fire damper control systems. When ambient temperatures reach the 165°F thermal threshold — a standard UL-recognized rating for fire damper applications — the fuse switch opens the circuit, triggering the damper to close and helping contain the spread of fire and smoke through ductwork.
Key Features
- 165°F (74°C) thermal trip rating — standard fire damper fusible link temperature
- Designed as a genuine Ruskin spare part (SP) for EFL series actuators
- Provides reliable, single-use thermal overcurrent protection
- Supports code-compliant fire damper operation in commercial and industrial HVAC systems
- Compact design for straightforward field replacement
Application
The EFL/SP100/165 fuse switch is used in conjunction with Ruskin electric fire damper actuators and related EFL series components. It serves as a critical safety element, ensuring that in the event of a fire, the damper actuator circuit is interrupted at the prescribed temperature, allowing the damper to fail-safe to the closed position. This component is ideal for replacement during routine maintenance, post-fire inspection, or system upgrades.
