Danfoss 060-5253 Pressure Control

The Danfoss 060-5253 is a high-performance dual pressure control designed for heavy-duty HVACR applications, serving as a direct technical replacement for legacy models 060-126866 and 060-525300. This unit features a 2SPDT switch configuration, allowing for independent signaling and control of both high-pressure and low-pressure sides. The low-pressure side offers a regulation range of 6" Hg to 108 psi with an adjustable differential of 10 to 60 psi, while the high-pressure side monitors from 100 to 600 psi with a fixed 60 psi differential. Built with fail-safe dual bellows, this controller prevents refrigerant loss and ensures system cutout if the inner bellows fail. The 1/4" Flare (MFL) connections and convertible reset functionality provide maximum flexibility for contractors in the field, making it a standard for protecting compressors against suction loss or excessive discharge pressure in commercial refrigeration systems.

• Enhanced System Protection: The fail-safe double bellows design triggers a premature cut-out in the event of a leak, preventing catastrophic equipment failure.
• Versatile Wiring: Equipped with 2SPDT contacts (Single Pole Double Throw), providing separate high and low pressure signals for advanced control circuits.
• Field Adjustability: Features convertible reset logic, allowing technicians to toggle between automatic and manual reset modes to match specific system safety requirements.
• Reliable Performance: High contact load capacity (up to 24 FLA at 240V) and ultra-short bounce times minimize electrical wear and arcing.
• Universal Compatibility: Designed for use with a wide range of refrigerants including R22, R134a, R404A, and R507A.

What is the difference between Danfoss 060-5253 and 060-126866?
The 060-5253 is the upgraded direct replacement for the 060-126866. It maintains the same 6"/108#L 100/600#H pressure ratings but includes modernized technical specs found in the KPU series.

Does this unit support manual or automatic reset?
This model features convertible reset. Technicians can set the reset function to either manual or automatic for both the high and low pressure sides during installation.

Is this control suitable for R410A systems?
Yes, the high pressure range of up to 600 psi makes it suitable for high-pressure refrigerants like R410A that require a higher cutoff point for safety.
