Liebert R13-0090S Limit switch
The Liebert R13-0090S Limit Switch is a critical safety component engineered for precision cooling systems and data center environmental controls. This OEM replacement part functions as a high-limit safety, monitoring discharge or supply air temperatures to prevent system overheating. With a specific 118-120F operating range, this switch provides an automatic reset (AUTO) function, ensuring that the circuit closes or opens once temperatures normalize within the calibrated threshold.
Designed for mission-critical HVACR applications, the Liebert R13-0090S is essential for maintaining strict thermal parameters in Vertiv/Liebert units. As a veteran technician knows, using the correct temperature-actuated switch is vital for protecting the heat exchanger and sensitive electronic components from thermal stress. This L120-2 automatic limit ensures seamless integration with existing control logic, offering reliable performance without the need for manual intervention after a temporary temperature excursion.
Key Benefits
- Precise Thermal Calibration: Factory-set for 118-120F operation to ensure accurate protection in high-stakes cooling environments.
- Automatic Reset Functionality: Eliminates the need for manual resets, reducing site visits and downtime for data center HVAC maintenance.
- OEM Compatibility: Specifically engineered for Liebert precision cooling units, ensuring matches for electrical ratings and physical mounting.
- High-Reliability Construction: Built to withstand the high-cycle demands of industrial-grade environmental control systems.
Common Questions
What causes a limit switch like the R13-0090S to trip frequently?
Frequent tripping is typically a symptom of restricted airflow, often caused by clogged filters, a failing blower motor, or obstructed return air paths in the Liebert unit.
Can I substitute this with a manual reset limit switch?
It is not recommended. The R13-0090S is an automatic limit switch; substituting it with a manual version changes the system's safety sequence and could cause unnecessary system lockouts.
How do I verify the operation of this switch during a service call?
Use a multimeter to check for continuity across the terminals. At room temperature, the switch should typically be closed, opening only when the 120F threshold is reached.
