Daikin-McQuay 300051281 Actuator

The Daikin-McQuay 300051281 Actuator is a 24V proportional electric actuator designed for precise modulation in commercial HVAC systems. This Schneider Electric TAC MF51-7103-784 equivalent provides reliable control for both damper and valve applications. Operating at 22VA (11W), it features a 15k-ohm feedback resistance for accurate positioning and system monitoring. For technicians performing retrofits, this unit is a direct replacement for several obsolete part numbers, including MF-5513-702, MF-5533-701, and MF-5533-702. When utilized as a damper actuator, it requires the P/N 300051282 linkage assembly. The 300051281 is engineered for longevity in high-demand environments, ensuring seamless integration with existing building automation controls. If your installation requires specific terminations, be sure to order P/N 4EGA9388 terminal connectors separately. This non-spring return actuator is the industry standard for maintaining stable air and fluid flow in Daikin-McQuay air handling units and chiller systems.

• Universal Compatibility: Replaces a wide array of legacy Daikin-McQuay actuators and Schneider Electric models like the 4EZS9191 and 4FAV9331.
• High-Precision Feedback: The integrated 15k-ohm feedback potentiometer allows for granular control and real-time positioning data.
• Flexible Installation: Dual-purpose design functions as a valve actuator or damper motor, reducing inventory complexity for common service calls.
• Robust Electrical Specs: Operates on standard 24V HVAC power supplies with a manageable 22VA power draw.

What is the direct cross-reference for the 300051281?
This actuator is identical to the MF51-7103-784 and the MF-5513-702. It is the primary replacement for obsolete 056610701 and 105600401 models.

Can I use this for a damper without additional hardware?
No, for damper applications, you must utilize the 300051282 linkage kit to ensure proper stroke and torque delivery.

Does this unit include terminal connectors?
The standard unit does not include terminal connectors. If your wiring configuration requires them, order P/N 4EGA9388.
