Danfoss 060-5244 Pressure Switch

The Danfoss 060-5244 is a professional-grade KPU 6B pressure switch designed for high-pressure cutout protection in commercial refrigeration and air conditioning systems. This dual-function control features a Single Pole Double Throw (SPDT) contact system, allowing for both system shutdown and alarm signaling upon reaching the setpoint. Engineered for reliability with HCFC and non-flammable HFC refrigerants, it operates within a range of 100 to 600 psig with a fixed differential. The 1/4 inch flare pressure connection ensures a secure, leak-proof mechanical joint, while the manual reset functionality provides critical safety by preventing automatic restarts after a high-pressure trip. This unit is housed in a robust enclosure, making it a standard choice for contractors requiring precise high-pressure limit control in demanding environments. Its vibration-resistant design and high-contact load capacity ensure long-term stability in industrial HVACR applications.

• Manual Reset Safety: Prevents equipment damage by requiring technician intervention after a high-pressure event.
• SPDT Contact Logic: Enables simultaneous compressor cutout and remote monitoring or alarm activation.
• Snap-Action Contacts: Minimizes arc-over and ensures consistent electrical performance under heavy loads.
• Precise Pressure Diaphragm: Maintains calibration accuracy even when exposed to high-pulsation environments.
• Universal Compatibility: Standard 1/4" flare fitting allows for seamless integration into existing refrigeration manifolds.

Is the Danfoss 060-5244 compatible with R-410A systems?

Yes, the KPU 6B is rated for high-pressure HFCs like R-410A, provided the operating pressures fall within the 100-600 psig setpoint range.

What is the difference between KPU and KPI series switches?

The KPU series is specifically optimized for refrigeration and air conditioning applications, whereas the KPI series is typically utilized for light industrial water and air systems.

How do I wire the SPDT terminals for a cooling application?

For standard high-pressure cutout, wire to the terminals that open on pressure rise. Use the remaining terminal for a lockout light or alarm circuit to notify the end-user of a trip.
