Schneider Electric MA40-7040 Spring Return Actuator 120V 2-Position 35 in-lb Direct Mount

The Schneider Electric (Barber Colman) MA40-7040 is a direct mount, spring return electric actuator designed for HVAC damper control applications. This robust actuator provides reliable 2-position control with 35 inch-pounds of torque, suitable for modulating air flow in commercial and industrial heating, ventilation, and air conditioning systems.

Key Specifications:

• Voltage: 120VAC operation for standard North American electrical systems
• Control Type: 2-position (open/close) spring return operation
• Torque Output: 35 inch-pounds of rotational force
• Mounting: Direct mount design for easy installation on damper shafts
• Spring Return: Automatic fail-safe positioning when power is removed

The spring return feature ensures the damper returns to a predetermined safe position during power failure, making this actuator ideal for life safety and smoke control applications. The direct mount configuration eliminates the need for additional mounting hardware, simplifying installation and reducing setup time. Barber Colman actuators, now part of the Schneider Electric family, are known for their durability and long service life in demanding HVAC environments.
