Schneider Electric MA4D-8033-100 Damper Actuator 2-Position 24V 30 lb-in

The Schneider Electric (Barber Colman) MA4D-8033-100 is a two-position spring return damper actuator designed for commercial HVAC applications requiring reliable zone control and air distribution management. This 24-volt actuator delivers 30 lb-in of torque, providing sufficient power for medium-sized dampers in air handling systems.

Key Features:

• Two-position spring return operation for fail-safe damper control
• 24VAC power supply for compatibility with standard HVAC control systems
• 30 lb-in (3.4 Nm) torque output suitable for dampers up to 8-10 square feet
• Plenum-rated cable for installation in air handling plenums and ductwork
• Durable construction for long service life in commercial applications
• Direct mounting capability to damper shafts with standard linkage
• Spring return ensures damper returns to normal position on power loss

This actuator is ideal for controlling zone dampers, bypass dampers, and outside air dampers in VAV systems, rooftop units, and air handlers. The plenum-rated cable meets building code requirements for in-plenum installation without additional conduit.
