Danfoss RT5A Pressure Switch | 4.0 to 17.0 bar | Manual Reset (Max.) | 017-504766

Product Description:

The Danfoss RT5A (017-504766) is a critical safety component designed for high-pressure monitoring in the UAE’s industrial sector. Featuring a Manual Reset (Max.) mechanism, this switch ensures that if system pressure exceeds the set limit (within the 4.0 to 17.0 bar range), the system is locked out and cannot restart until a manual intervention is performed—a vital safety protocol for Dubai’s industrial cooling facilities. Built with an IP66-rated enclosure, it is highly resistant to dust, moisture, and the corrosive ammonia environments typical of UAE cold storage. Its heavy-duty SPDT contact system and robust bellows design ensure long-term reliability and precise trip points under the extreme ambient heat of the Middle East.

Key Features & Benefits:

• Fail-Safe Manual Reset: Provides maximum safety by requiring a technician to manually reset the device after a high-pressure trip in UAE plants.
• Industrial High-Pressure Range: 4 to 17 bar regulation range is ideal for discharge-side protection of UAE industrial compressors.
• Ammonia Compatible: Specifically designed for use with Ammonia (R717) and other fluorinated refrigerants used throughout the UAE.
• Rugged IP66 Housing: Offers superior protection against the harsh coastal air and sandy conditions of the UAE.
• High Repeatability: Ensures the safety limit is triggered at the exact setpoint every time, protecting expensive UAE infrastructure.

FAQs:

• Q: Why is the Manual Reset version (017-504766) required for UAE industrial plants?
• A: It acts as a safety “watchdog” that forces an inspection after an overpressure event, preventing repeated cycling that could lead to catastrophic failure in UAE systems.
• Q: Can this be used in maritime cooling systems in Dubai?
• A: Yes, the RT series is marine-approved and built to withstand the high vibration and salty air of the UAE‘s shipping industry.
• Q: What happens if the pressure drops below the setpoint?
• A: Because this is a Manual Reset (Max.) model, the switch will remain tripped until the reset button is pushed, even if the pressure returns to normal in the UAE system.
