Description
The Schneider Electric (Barber Colman) MP-453 is a heavy-duty proportional actuator engineered for precise damper and valve control in commercial HVAC and building automation applications. Delivering 220 lb-in of torque at 120 V, this actuator provides the muscle needed to drive large dampers and valves with accuracy and reliability.
Key Features
- 120 V operating voltage for compatibility with standard commercial control circuits
- 220 lb-in torque output for reliable actuation of large dampers and valves
- 40-second timing (no load) for smooth, controlled positioning
- Non-spring-return design — holds last position on power loss
- SPDT auxiliary switch for end-of-travel status signaling and interlocking
- 90-degree rotation for full quarter-turn damper and valve operation
- Proportional control for precise modulating response to control signals
Application
The MP-453 is ideal for use in VAV systems, air handling units, and hydronic systems where proportional modulation and dependable torque are required. The built-in SPDT auxiliary switch enables easy integration with building automation systems, providing end-of-travel feedback for sequencing or alarm functions.
