Danfoss 060-5231 Control

The Danfoss 060-5231, also known as the KPU1 Low Pressure Switch, is a heavy-duty automatic reset pressure control engineered for precision monitoring in commercial HVACR refrigeration systems. This SPDT pressure switch features a 6-inch capillary tube and a 1/4" male flare connection, facilitating direct integration into suction lines to protect compressors against low-pressure conditions. With a regulation range of 6” Hg to 108 PSI and an adjustable differential of 10 to 60 PSI, it provides the versatility required for various commercial air conditioning applications. The Danfoss KPU1 060-5231 is housed in a NEMA 1 enclosure and rated for ambient temperatures between -40°F and 122°F, ensuring reliable HVAC system protection in demanding mechanical environments. Contractors utilize this refrigeration pressure control for starting and stopping compressors or condenser fans, leveraging its high 144A LRA contact rating for robust electrical performance.

• Versatile Compatibility: Fits standard 1/4" male flare fittings, making it a reliable drop-in for most refrigeration system pressure controls.
• Automated Protection: The automatic reset function reduces downtime by restoring system operation once pressure stabilizes within the set differential.
• Precise Control: Features clear differential and range scales for accurate setpoint adjustments in the field without guessing.
• Rugged Construction: Built with phosphor bronze bellows and silver contacts to ensure long-term mechanical reliability and chatter-free electrical switching.
• Flexible Wiring: The SPDT (Single Pole Double Throw) contact arrangement allows for dual-purpose alarm signaling or component cycling.

• What is the maximum working pressure for the Danfoss 060-5231? This control is designed for a maximum working pressure of 250 PSIG and has been tested up to 290 PSIG to ensure safety during system surges.
• Can this switch be used for liquid line applications? No, this low pressure control is specifically designed for gaseous media and is not intended for liquid line sensing.
• What refigerants are compatible with the KPU1? It is suitable for non-corrosive, oil-free refrigerants including R134a, R513A, and R515B, as well as common HCFC and HFC gaseous fluids.
