Product details
Danfoss RT260A Differential Pressure Switch | 0.5 to 4 bar | Manual Reset | 017D002366
Product Description: The RT260A (017D002366) monitors the pressure difference between two points, most commonly used for oil pressure safety in large refrigeration compressors. In the UAE’s intensive cooling environments—such as district cooling plants or large cold storage facilities in Jebel Ali—maintaining correct lubrication pressure is vital. This model features a regulation range of 0.5 to 4 bar and includes a manual reset function. The manual reset ensures that if the pressure differential drops below the safe limit, the system remains locked out until a technician can inspect the cause, providing an essential layer of protection against compressor failure.
Key Features & Benefits:
- Ammonia (R717) Ready: Constructed with materials specifically resistant to ammonia corrosion, ideal for the UAE’s largest industrial refrigeration systems.
- Safety Manual Reset: Prevents automatic restarting of equipment after a fault, protecting high-value compressors from running without sufficient oil pressure.
- IP66 Protection: The rugged enclosure is dust-tight and protected against powerful water jets, ensuring reliability in the humid and dusty conditions of the Middle East.
- High Repeatability: The RT series is world-famous for its long-term stability and precise switching, even after years of operation in vibrating plant rooms.
- Versatile Media: Compatible with R717, HCFC, and non-flammable HFC refrigerants.

FAQs:
- Q: What is the difference between this and the RT262A?
- A: The RT260A has a lower range (0.5–4 bar) typically used for oil pressure, while the RT262A has a higher range (0.1–1.5 bar) often used for filter monitoring or flow control.
- Q: Is the 017D002366 suitable for outdoor installation in Dubai?
- A: Yes, the IP66 rating means it is well-protected against the elements, though a sunshield is always recommended for electronic/mechanical controls in the UAE heat.
- Q: Can it be used in marine applications in Abu Dhabi?
- A: Absolutely. Its robust construction and high enclosure rating make it suitable for the corrosive and humid environments of the maritime industry.
