Nibe Low Pressure Switch (Part No. 518717)

• Part Number: 518717

• Description: This is a low-pressure safety switch (sometimes called a low-pressure stat or sensor) designed for use in the refrigerant circuit of NIBE heat pumps. Its role is to monitor the pressure level and protect the compressor and other components by stopping the unit if refrigerant pressure drops below the safe threshold.

• Function:

  • Cuts off the compressor operation if refrigerant pressure falls too low.

  • Prevents damage due to leaks, undercharging, or system malfunctions.

  • Ensures the system runs within manufacturer-specified pressure limits.

🔧 Compatibility with NIBE F1330 (Various kW Models)

The NIBE F1330 is a modular ground source heat pump series available in different capacities (e.g., 22, 30, 40, kW). Each size generally shares the same pressure safety controls, though it’s always best to cross-check for your specific kW model.

✅ Confirmed Compatibility:
Yes, the NIBE 518717 low-pressure switch is listed as compatible with the NIBE F1330 series, across various capacities. This includes:

• F1330-22

• F1330-30

• F1330-40
  

This part is typically used as the standard replacement for failed or worn low-pressure switches on these models.
