Description
The Schneider Electric (Barber Colman) MP-452 is a heavy-duty proportional actuator engineered for precise damper and valve control in commercial and industrial HVAC applications. Delivering 220 lb-in of torque at 120 V, this actuator provides reliable, accurate positioning across a full 180-degree rotation range — making it well-suited for demanding building automation and air handling systems.
Key Features
- Proportional control for precise modulating positioning
- 120 V operating voltage for compatibility with standard commercial control systems
- 220 lb-in torque output for reliable actuation of heavy-duty dampers and valves
- Adjustable timing range of 80–800 seconds (no load) for flexible application tuning
- Non spring return design — maintains last position on power loss
- Built-in SPDT auxiliary switch for end-of-travel feedback and interlock wiring
- 180-degree rotation for broad damper and valve compatibility
Application Highlights
- Ideal for commercial HVAC air handling units, VAV systems, and zone dampers
- Compatible with building automation and DDC control systems
- Designed as a direct replacement for legacy Barber Colman MP-452 actuators
- Suitable for modulating control of two-position and proportional valve assemblies
