Ruskin RUS-M120 Actuator

For contractors servicing commercial control dampers and operable louvers, the Ruskin RUS-M120 Actuator serves as a direct-coupled, 120V on/off motorized actuator engineered for precise airflow regulation. This spring return actuator is designed for factory or field mounting on dampers up to 12 sq. ft. (with seals) or 24 sq. ft. (without seals). Utilizing a universal clamp, it mounts directly to shafts ranging from 5/16" to 5/8" (8 to 16 mm), making it a versatile drop-in for CD36 damper assemblies and similar HVAC frames. The RUS-M120 features electronic stall detection across its entire 90-degree rotation, protecting the motor from burnouts during overload conditions without the need for mechanical end switches. Its reversible mounting design allows for fail-safe positioning—either spring-closed or spring-open—simply by flipping the unit. With a drive time of 55 to 71 seconds and a spring return time of under 26 seconds, this Ruskin damper actuator ensures efficient and reliable operation in HVAC automation systems. Integrated support for 3/8" flexible metal conduit simplifies electrical line-voltage connections on the job site.

Key Benefits of the Ruskin RUS-M120
  • Universal Compatibility: Mounts directly to 5/16" to 5/8" diameter shafts for quick field replacement.
  • Enhanced Durability: Electronic stall detection prevents motor failure under high-load or obstructed conditions.
  • Dual Orientation: Reversible design supports both clockwise and counter-clockwise spring-return fail positions.
  • Direct Drive Power: High-torque 120VAC operation suitable for square-foot face areas up to 24 sq. ft.
  • Job-Site Efficiency: Simple universal clamp and conduit ready for faster contractor installation.
Common Questions Regarding the RUS-M120

What is the maximum damper size this actuator can handle?
The Ruskin RUS-M120 is rated for control dampers up to 12 square feet when blade and jamb seals are present, or up to 24 square feet for dampers without seals.

Can I change the fail-safe direction in the field?
Yes. The actuator is designed to be reversible. By uncoupling the unit and flipping it over to the opposite face, you can select whether the damper returns to the open or closed position upon loss of power.

Are there built-in auxiliary switches?
While the standard RUS-M120 is an on/off actuator, an optional "-S" model variant includes integral auxiliary switches for end-stop position indication or peripheral switching.
