Danfoss 060-311066 Pressure Control

The Danfoss 060-311066 is a professional-grade KP5 pressure control designed for heavy-duty regulation and monitoring in refrigeration and air conditioning systems. This high-side pressure switch operates within a 0 to 25 bar range (approx. 0 to 363 psig) and features a single pole double throw (SPDT) contact system, allowing for direct control of single-phase AC motors up to 2 kW or as a pilot switch in larger circuits. Its ultra-short bounce time—achieved through a snap-action function—minimizes contact wear and increases reliability under high-load cycles. Engineered for versatility, it is compatible with fluorinated refrigerants (HCFC and non-flammable HFC) and uses 1/4-inch flare connections for secure integration. The unit includes an IP44 rated enclosure when mounted on a flat surface, protecting internal components from dust and water splashes. Technicians value the KP5 series for its vibration-resistant design and the manual trip function that allows for contact testing without specialized tools.

Key Technical Benefits

• Precise Pressure Regulation: Features a manual reset or automatic functionality depending on system configuration, providing critical high-pressure protection.
• Adjustable Differential: The 1.8 to 6 bar adjustable differential allows for fine-tuning system cycling to prevent short-cycling and reduce compressor wear.
• Robust Build Quality: High-quality bellows technology ensures long-term calibration stability even in high-vibration environments.
• Easy Installation: Compact footprint and clear scale setting allow for rapid commissioning and maintenance in tight mechanical rooms.
• Broad Compatibility: Rated for a wide temperature range, making it suitable for both commercial refrigeration and process cooling applications.

Common Installation & Operation Questions

What is the maximum working pressure for this control?
The Danfoss KP5 060-311066 has a maximum working pressure (MWP) of 35 bar (510 psig), ensuring safety margins during system pressure spikes.

Can this switch be used for low-pressure applications?
No, this model is specifically calibrated for the high-pressure side. For low-pressure suction monitoring, a Danfoss KP1 or KP2 series should be utilized.

How do the electrical contacts handle inductive loads?
The SPDT switch is designed to handle an inductive motor load of 16A at 400V, making it capable of managing most commercial fan motors and compressors directly.
