Danfoss RT6AB High Pressure Switch | 10 to 28 bar | Manual Reset | 017-503566

Product Description:

The RT6AB (017-503566) serves as a critical safety limit switch for high-pressure monitoring. In the UAE—where massive ammonia plants for food processing and cold storage in Jebel Ali operate under high thermal stress—this switch protects the system by cutting out the compressor if the discharge pressure exceeds safe limits (up to 28 bar). The Manual Max Reset function is a vital safety feature: once the switch trips due to high pressure, a technician must manually inspect the system and reset the device, preventing hazardous automatic restarts. Its IP54-rated enclosure ensures reliable operation in the humid and dusty plant rooms typical of the Middle Eastern industrial sector.

Key Features & Benefits:

• Ammonia (R717) Compatible: Equipped with stainless steel bellows that are immune to the corrosive effects of ammonia.
• Safety Manual Reset: Ensures that high-pressure faults are investigated by a professional before the system can be restarted.
• Wide Regulation Range: Covers 10 to 28 bar, ideal for high-side pressure protection in R717, R404A, and R507 systems.
• High Reliability: The RT series is known for its legendary durability and mechanical precision in vibrating industrial environments.
• Vast Application: Suitable for both land-based industrial refrigeration and maritime cooling systems across the UAE.

FAQs:

• Q: Why use RT6AB instead of a standard KP switch in the UAE?
  • A: While KP switches are common, the RT series (like RT6AB) is built for more rugged industrial use, offering higher precision and better resistance to the harsh, corrosive environments found in ammonia plants.
• Q: Can this be used for R410A systems?
  • A: Yes, its 28-bar range and 34-bar max working pressure are compatible with many R410A high-side safety applications.
• Q: Is the reset button easy to access?
  • A: Yes, the reset button is located on the top of the housing, allowing for easy manual intervention by UAE maintenance teams.
