Danfoss 060-5243 Pressure Control

The Danfoss 060-5243, also identified as the KPU 6W pressure control, is an industrial-grade safety switch designed for high-pressure monitoring in HVACR systems. This unit features a single pole double throw (SPDT) contact system, providing versatile wiring options for either compressor cycling or high-pressure cutout applications. Engineered for reliability with HCFC and non-flammable HFC refrigerants, the KPU 6W operates within a wide pressure range, specifically 100 to 600 psig, with a fixed differential of approximately 60 psi. The automatic reset function ensures system continuity once pressures normalize, reducing unnecessary downtime. Connections are simplified via a standard 1/4 inch flare nut (internal thread), allowing for a secure, leak-free mechanical joint. Its robust snap-action mechanism minimizes contact bounce and internal wear, even under high vibration or rapid cycling conditions common in commercial refrigeration racks. For technicians, this Danfoss pressure switch represents a standard for safeguarding liquid or gas lines against over-pressurization.

Key Benefits

• Universal Compatibility: Optimized for use with high-pressure refrigerants like R-410A and R-404A.
• Vibration Resistant: The snap-action contact system prevents arcing and ensures reliable electrical signaling in high-vibration environments.
• Easy Installation: Features a standard 1/4" female flare connection, eliminating the need for specialized brazing in most retrofit scenarios.
• Field Reliability: High contact load capacity allows for direct control of single-phase AC motors up to 2 kW or pilot duty circuits.
• Compact Footprint: Designed for tight mechanical rooms and internal compressor housing mounting.

Common Questions

How do I wire the KPU 6W for high-pressure cutout?
Utilize the SPDT contacts by connecting to the terminals that open on pressure rise. This breaks the control circuit to the contactor coil when the system exceeds the 600 psi threshold.

Is the 1/4 inch flare connection compatible with copper capillary sets?
Yes, the 1/4" F flare nut integrates directly with standard 1/4" refrigeration hoses or copper capillary tubes equipped with a male flare fitting.

Can this control be used for low-pressure applications?
No, the Danfoss KPU 6W is specifically calibrated for high-pressure safety limits. For low-side monitoring, a KPU 1 or KPU 2 series control should be utilized instead.
