What is the operating pressure at which the High Pressure Switch opens on an R-410A system?

The operating pressure at which the High Pressure Switch opens on an R-410A system is typically around 610 psig. This safety feature is crucial for preventing the system from operating at excessive pressures, which could potentially lead to component failures or even system damage. The High Pressure Switch acts as a protective measure, ensuring that when pressure exceeds this designated threshold, the system shuts down to avoid hazards.

Understanding that the High Pressure Switch opens at 610 psig highlights the importance of maintaining proper refrigerant levels and ensuring that the system is functioning within its design specifications. Systems operating with pressures higher than this could indicate issues such as overcharging or a malfunctioning component, which necessitates immediate attention to prevent further complications.
