Danfoss 060L5208 KPU73 Temperature Control

The Danfoss 060L5208 KPU73 Temperature Control is a rugged, SPDT (Single Pole Double Throw) thermostat engineered for precision regulation in commercial refrigeration and HVAC applications. With an adjustable range of -20°F to 60°F and a reliable automatic reset function, this control is a standard for technicians managing walk-in coolers, freezers, and air conditioning systems. The unit utilizes an adsorption charge, which ensures high sensitivity and accurate switching regardless of whether the 80-inch capillary or bellows is warmer or colder than the sensing bulb.

Designed for heavy-duty cycling, the KPU73 offers high contact load ratings (24 FLA / 144 LRA at 120/240V AC), making it suitable for direct motor control or pilot duty in larger systems. The NEMA 1 enclosure provides a durable housing for wall-mounting, while the 1/2-inch conduit entry point simplifies field wiring and integration into existing control circuits. This 060L5208 model is optimized for low-temperature applications where maintaining a strict differential is critical for compressor longevity and product safety.

• Versatile Control Logic: Features SPDT contact function, allowing for simultaneous control of compressors, fans, or alarm circuits based on temperature rise or fall.
• Flexible Installation: Equipped with an 80-inch capillary tube and a remote 3/8" x 3 3/8" bulb to reach deep into evaporators or storage areas.
• Stable Calibration: The adsorption charge design maintains temperature control accuracy even in environments with varying ambient temperatures at the housing.
• Industrial Strength: High electrical ratings allow for direct control of single-phase AC motors without the immediate need for auxiliary contactors.

What is the difference between adsorption and vapor charges in Danfoss KPU units?
An adsorption charge, like that in the Danfoss 060L5208, allows the bulb to be placed regardless of the ambient temperature at the bellows or capillary. Vapor charges require the bulb to be the coldest part of the system to maintain accuracy.

Can the differential be adjusted on this model?
Yes, this unit features an adjustable differential typically ranging from 5°F to 50°F at the high end, providing flexibility to prevent short-cycling of refrigeration equipment.

Is this control suitable for outdoor use?
The standard enclosure is rated NEMA 1, meaning it is intended for indoor use. For outdoor applications, it should be installed within a secondary weather-protected housing.
