Schneider Electric (Barber Colman) MA41-7150 Actuator

The Schneider Electric (Barber Colman) MA41-7150 Actuator is a high-torque 120V 2-position spring return actuator engineered for precise fail-safe control in commercial HVAC systems. Delivering a significant 133 in-lb torque (15 N-m), this SmartX DuraDrive series unit is the industry-standard direct replacement actuator for discontinued models including the MA-6501, MA-7501, MA40-7150, and MA40-AF120. Designed for versatility, it supports direct-coupled mounting to both round and square damper shafts, ensuring a secure mechanical connection without complex linkages. Field reliability is reinforced by its rugged die-cast NEMA 2 enclosure and internal overload protection, which prevents motor burnout at the end of rotation or in stall conditions. This DuraDrive MA41-7150 is a critical component for contractors maintaining legacy Barber Colman systems, providing a seamless retrofit path for air handling units and large volume control dampers.

Key Benefits

• Universal Compatibility: Serves as the primary replacement for MA-6501 and MA-7501 series, maintaining existing footprint and control logic.
• Enhanced Torque Performance: Features a 133 in-lb rating capable of driving large dampers or valves even against high static pressure.
• Mechanical Fail-Safe: Reliable spring return functionality ensures dampers return to their original position during power loss for critical building safety.
• Durable Construction: Built with a die-cast housing rated for NEMA 2/IP54, providing protection against environmental debris and moisture.
• Simplified Installation: The direct-coupled design eliminates the need for external linkages, reducing labor time for HVAC actuator retrofits.

Common Questions

Is the MA41-7150 compatible with older Barber Colman 120V systems?
Yes, this Schneider Electric MA41-7150 is specifically designed as the direct upgrade and technical successor to the MA-6501 and MA-7501 legacy series.

Does this actuator require an external end switch?
This specific model is a standard 2-position unit. If your application requires auxiliary signaling, verify if your existing setup utilized the -502 sub-model which includes internal switches.

What damper shaft sizes does the universal clamp accept?
The factory-installed clamp on the MA41-7150 typically accommodates round shafts up to 3/4" and square shafts up to 1/2". For larger shafts up to 1.05", an AM-687 accessory clamp may be required.
