Aaon R64260 Relay

The Aaon R64260 Relay is a heavy-duty overload protection relay designed for precise motor circuit safeguarding in commercial HVACR systems. Characterized by its adjustable 24A-40A current range, this thermal-magnetic component is engineered to prevent motor burnout by monitoring current draw and tripping before damage occurs due to overcurrent or phase loss. Technicians often rely on this specific relay for maintenance on high-tonnage Aaon rooftop units and air handlers where consistent amperage monitoring is critical to system longevity. The design facilitates seamless integration into existing motor control circuits, ensuring compatibility with standard contactors. Utilizing a robust construction typical of industrial-grade HVAC motor starters, the R64260 provides reliable thermal overload protection, minimizing downtime by offering field-adjustable settings to match specific motor nameplate data for optimized compressor protection and fan motor safety.

Key Technical Benefits:

• Broad Amperage Range: Field-adjustable 24A to 40A setting allows for precise calibration to specific Full Load Amps (FLA) requirements.
• Motor Integrity: Prevents catastrophic failure by detecting prolonged overcurrent conditions in commercial HVAC equipment.
• Simplified Integration: Direct-mount compatibility reduces installation time in control cabinets and electrical panels.
• Phase Loss Sensitivity: Protects multi-phase motors from damage during unbalanced electrical loads or phase dropouts.

Common Technical Questions:

How do I set the correct amperage on the Aaon R64260?
Rotate the adjustment dial to match the Motor Nameplate FLA. Do not exceed the rated capacity of the motor or the relay to ensure proper overload trip curve performance.

Is the R64260 compatible with all Aaon rooftop units?
This relay is sized for specific 24A-40A applications. Verify your wiring diagram and motor starter requirements to ensure the current range aligns with your unit's electrical specifications.

Can this relay be used for manual or automatic reset?
The R64260 typically features a selectable reset mode, allowing technicians to choose between manual intervention for troubleshooting or automatic reset for remote applications.
