Schneider Electric (Barber Colman) MA-5330 Actuator

The Schneider Electric (Barber Colman) MA-5330 is a high-performance hydronic actuator designed for the two-position control of dampers and globe valves in demanding HVACR applications. This 120V spring return actuator features a robust oil-immersed motor and pump assembly, providing a consistent 20 lb-in torque output for reliable fail-safe operation. As a direct replacement for MA-5220 and MA-5330-0-0-3 models, it integrates seamlessly into existing systems requiring SPST control signals. The unit's NEMA 1 die-cast lower housing and painted steel upper housing ensure durability in mechanical rooms, while the 15-second spring return timing provides rapid closure upon power interruption. With a power rating of 18VA (14 Watts) and a 4-foot appliance cable included, this two-position damper actuator is built for heavy-duty commercial service, maintaining operation in ambient temperatures ranging from -40 to 140°F.

• Direct Retrofit Compatibility: Engineered as the primary MA-5220 replacement, reducing downtime during field service calls.
• Fail-Safe Reliability: Mechanical spring return ensures dampers or valves return to their normal position during power loss.
• Industrial Construction: Features a hydraulic actuator design with an oil-immersed motor for extended service life in high-cycle environments.
• Standardized Installation: Includes 1/2-inch conduit openings and color-coded leads for straightforward wiring to 120Vac systems.

Can the MA-5330 be used for both damper and valve applications?
Yes, this model is versatile; it can be used for damper control or paired with appropriate linkages for globe valve applications.

Does this unit replace the older Barber Colman MA-5200 series?
The MA-5330 is the current technical successor and direct replacement for the MA-5220 and MA-5200 series actuators with 120V requirements.

What is the torque rating for this specific model?
This actuator provides a rated torque of 20 lb-in, suitable for small to medium-sized dampers and standard valve assemblies.
