Danfoss 060-5248 Control

The Danfoss 060-5248 (Model KPU 15) is a heavy-duty dual pressure control designed for precise regulation and safety monitoring in commercial refrigeration and air conditioning systems. This unit features a Single Pole Double Throw (SPDT) contact system, providing a versatile interface for both high-pressure and low-pressure limiting. Built as a direct replacement for 099009 and 060-524800, it ensures a seamless fit for technicians performing field retrofits or repairs. It operates with a low-pressure range of 6" Hg to 108 psig and a high-pressure range of 100 to 465 psig, offering broad application flexibility across various HVACR systems. The 36-inch capillary tube with a 1/4-inch female flare nut allows for flexible mounting, while the automatic reset function on both sides ensures continuous system operation once pressures return to safe operating parameters. This pressure switch is optimized for use with common HCFC, HFC, and non-flammable refrigerants, making it a reliable standard for modern mechanical controls.

• Universal Compatibility: Engineered as a functional cross-reference for multiple legacy models, including 099009, 060-524800, O12-1549, and P170LB-1C.
• High-Performance Bellows: Durable internal bellows technology provides excellent vibration stability and long-term mechanical reliability under harsh compressor cycles.
• Flexible Installation: Features a 36" capillary and standard 1/4" flare connection to accommodate complex piping layouts in commercial cabinets.
• Precise Adjustment: Dual scales allow for independent setting of high and low trip points to safeguard compressors against loss of charge or excessive discharge pressure.

How do I set the trip points on the Danfoss KPU 15?
The low-pressure cut-in and high-pressure cut-out can be adjusted via the top spindles. Always use a calibrated manifold gauge to verify the mechanical scale settings against actual system pressures during commissioning.

Is this control compatible with R-410A systems?
Yes, the high-pressure limit of 465 psig is rated for the operating envelopes of R-410A, R-404A, and R-134a systems, provided the discharge pressure does not exceed the maximum test pressure of the unit.

What is the purpose of the 36-inch capillary tube?
The extended capillary provides a vibration-dampening connection between the pressure tap and the control body, reducing mechanical stress on the bellows and allowing the switch to be mounted in a more accessible location for monitoring.
