Schneider Electric (Barber Colman) MP-9430 Motor

The Schneider Electric (Barber Colman) MP-9430 is a heavy-duty electric actuator engineered for high-torque damper control and valve positioning in commercial HVACR systems. As a direct, identical replacement for the Barber Colman EA-71, this motor provides 550 lb-in of torque, making it a reliable solution for driving large dampers and industrial valve actuators. Operating on a 120V AC power supply, it features a fixed 90-degree rotational stroke with a 20-second travel time, ensuring precise, repeatable positioning for modulating or two-position control applications. Its oil-immersed motor and gear train provide superior thermal dissipation and durability in demanding environments.

Key Benefits:

• High Torque Output: Delivers 550 lb-in (62.2 Nm) to handle medium-duty industrial dampers and large globe valves without stall.
• Standardized Timing: Fixed 20-second stroke speed allows for consistent system synchronization and response profiles.
• EA-71 Compatibility: Functionally identical to the legacy EA-71 motor, facilitating drop-in replacement without extensive linkage modification.
• Rugged Construction: Features a die-cast aluminum enclosure and internal SPDT auxiliary switch for position feedback and interlocking.
• Non-Spring Return: High-performance induction motor holds position upon signal loss, preventing sudden system fluctuations.

Common Questions:

Is the MP-9430 a direct replacement for the legacy Barber Colman EA-71?
Yes, the MP-9430 and EA-71 are technically identical in performance, torque rating (550 lb-in), and mounting footprint, making them interchangeable for existing field installations.

Can the timing or stroke angle be field-adjusted?
No, this specific model features a fixed 20-second travel time and a 90-degree stroke limit determined by the internal gearing; for adjustable strokes, refer to the MP-9700 or MP-4000 series.

What is the primary application for this actuator?
It is widely used for economizer damper control, inlet vane control, and high-pressure steam or water valve actuation in air handlers and large-scale mechanical rooms.
