Danfoss 060-5246 Pressure Control

The Danfoss 060-5246 (KPU6B) is a heavy-duty high pressure control engineered for critical protection in commercial refrigeration and air conditioning applications. Designed to replace legacy models like the 060-524600, this SPDT pressure switch features a robust manual reset mechanism that ensures a technician investigates system faults before restarting the compressor. With a wide regulation range of 100 to 600 psig and a fixed 60 psi differential, this Danfoss KPU6B provides precise high-side cut-out monitoring for fluorinated refrigerants (HCFC and non-flammable HFC). The unit includes a 36-inch capillary tube with a 1/4 inch flare nut for flexible mounting and a high-visibility contrast scale for accurate field adjustments. Built to industrial standards with an IP30 enclosure and a high contact rating (24A FLA), it allows for direct control of single-phase motors or integration into a control circuit via its Single Pole Double Throw contacts.

• Enhanced System Protection: The manual reset KPU6B stops operation during excessive discharge pressure events, preventing terminal compressor failure.
• Service Compatibility: Replaces 060-524600 and functions as a high-tier alternative to many Penn, Ranco, and Alco pressure switches.
• Reliable Contact Action: Features SPDT contacts for versatile wiring as either a high-pressure cut-out or a high-pressure alarm signal.
• Field-Proven Durability: Equipped with a 36" capillary to withstand vibration and provide versatile installation options in crowded mechanical rooms.
• High Electrical Capacity: Rated for 24A at 120V AC, permitting direct motor control without always requiring an external contactor.

What refrigerants is the Danfoss 060-5246 compatible with?
This control is optimized for use with most common HCFC and HFC refrigerants. It is not recommended for ammonia (R717) or flammable refrigerants.

How do I adjust the cut-out set point on a KPU6B?
The cut-out pressure is set by turning the range screw clockwise to increase the set point. Use a pressure gauge for final verification, as the internal scale is for reference only.

Can this switch be used for condenser fan cycling?
While KPU switches are versatile, this specific model (KPU6B) is typically utilized as a high-limit safety cut-out due to the manual reset feature. For fan cycling, an automatic reset model like the KPU6W is generally preferred.
