Schneider Electric (Barber Colman) M573-3520 Actuator

The Schneider Electric (Barber Colman) M573-3520 Actuator is a heavy-duty pneumatic damper actuator designed for precise proportional or two-position control in commercial HVAC systems. This piston damper actuator features a substantial 3-inch stroke and is factory-calibrated with a 5 to 10 psi spring range, making it ideal for managing airflow in multi-zone units, fan coils, and large mixing boxes. Engineered for durability, the M573-3520 is a direct functional equivalent to the 2473-230, ensuring a seamless drop-in replacement for legacy Barber Colman pneumatic setups without the need for extensive field modifications.

For efficient installation, this post-mounted actuator utilizes a standard 1/4-inch O.D. barbed fitting for secure pneumatic line connection. Its robust construction provides the necessary force to actuate dampers across diverse ventilation environments, maintaining consistent pressure response. Whether you are retrofitting an older mechanical room or servicing an existing I/A Series pneumatic loop, the Schneider Electric M573-3520 delivers the high-torque performance required to maintain tight environmental control. Technicians should note that this unit is designed for post mounting and includes the necessary clevis for linkage attachment.

• Direct Cross-Reference: Fully compatible and identical to the 2473-230 for easy legacy system maintenance.
• Precision Range: The 5-10 psi spring operating range allows for accurate proportional control of dampers and valves.
• Robust Stroke: 3-inch piston stroke provides ample travel for diverse HVAC damper configurations.
• Installation Ready: Post-mount design with pre-installed clevis simplifies mounting in tight mechanical spaces.
• Pneumatic Reliability: Designed for high-cycle industrial and commercial airflow applications.

Is the M573-3520 a direct replacement for the 2473-230?
Yes, the M573-3520 and 2473-230 are technically identical units used across Barber Colman and Schneider Electric product lines.

What is the maximum supply air pressure for this actuator?
While the spring range is 5-10 psi, the actuator typically operates on a nominal 20 psig supply, with a maximum safe pressure limit of 30 psig.

What type of mounting is required?
This specific model is designed for post mounting. If you require a right-angle bracket or different mounting hardware, please verify the specific kit requirements for your damper frame.
