Danfoss 060-5249 Pressure Control

The Danfoss 060-5249 Pressure Control, also known by the KPU15B model designation, is a heavy-duty dual pressure switch engineered for the rigorous demands of commercial refrigeration and air conditioning systems. This unit provides essential protection against excessively low suction pressure and high discharge pressure, functioning as a critical safety cutoff for the compressor. The low-pressure side features an adjustable range of 6" Hg to 108 psig with an automatic reset, while the high-pressure side operates between 100 and 465 psig with a manual reset to ensure a technician inspects the system after a high-limit event. Designed with 1/4" male flare connections, it offers seamless integration into standard manifolds. The SPST contact function (specifically NO+NC) is built to handle high electrical loads with minimal bounce time, preserving the longevity of your control circuits. Whether you are performing a 060-524900 replacement or a new installation, this control ensures precise setpoint stability even in high-vibration environments.

• Enhanced System Safety: Provides simultaneous monitoring of suction and discharge lines to prevent compressor failure.
• Technical Precision: Features manual reset on the high-pressure side to mandate a physical system check after a critical cut-out.
• Broad Refrigerant Compatibility: Suitable for a wide range of common refrigerants including R22, R134a, R404A, and R507.
• Durable Construction: High-resistance bellows and robust contact blocks are designed to withstand rapid pressure pulsations.
• Easy Installation: Standard 1/4" flare pressure connection simplifies field replacement for existing Danfoss or competitive controls.

What is the difference between Danfoss KP15 and KPU15B?
The KPU15B is a North American-specific variant of the KP series, often featuring a 1/4" flare connection and specific pressure ranges (6"/108# Low, 100/465# High) tailored for US HVACR standards.

How do I adjust the differential on this switch?
The low-pressure side has an adjustable differential range of 10 to 60 psi, while the high-pressure side typically features a fixed differential of approximately 60 psi to ensure proper system stabilization before manual reset is possible.

Can this be used for ammonia applications?
No, the Danfoss 060-5249 is designed for fluorinated refrigerants. For ammonia (R717) systems, a specific stainless steel bellows version is required.
