Danfoss 017-520366 Pressure Control

The Danfoss 017-520366 is a professional-grade RT116 pressure switch designed for heavy-duty applications in industrial and marine HVACR environments. This robust bellows actuated pressure control operates within a regulation range of 14.5 to 145 psig (1 to 10 bar), providing reliable SPDT contact function for demanding system automation. Built with an IP66 enclosure rating, it resists dust and high-pressure water jets, making it suitable for plant rooms and outdoor exposures. The unit features an adjustable differential range of 4.8 to 18.9 psi, allowing technicians to fine-tune industrial pressure switch settings to prevent short-cycling and ensure stable compressor or pump operation. With its 3/8-inch G-threaded male connection and dual Pg 13.5 cable entries, this Danfoss RT series controller integrates seamlessly into existing piping and electrical layouts, maintaining high repeat accuracy even after decades of service in high-vibration or corrosive atmospheres.

• Versatile Media Compatibility: Suitable for use with air, fresh water, and common fluorinated refrigerants, as well as ammonia (NH3) applications.
• Extreme Durability: The heavy-duty bellows system is rated for a maximum working pressure of 320 psig and a test pressure of 363 psig.
• Environmental Resilience: Engineered to function in ambient temperatures ranging from -58°F to 158°F (-50°C to 70°C).
• High Electrical Capacity: Features a robust contact system capable of handling AC-1 (ohmic) loads up to 10A at 400V.

What is the reset type for the 017-520366?
This specific model is equipped with an automatic reset function. Once the pressure moves beyond the set point and differential, the switch will automatically return to its original state.

Can this switch be used in marine environments?
Yes, the RT116 series carries extensive marine approvals (including GL, LR, DNV, and BV), making it a standard choice for maritime engine rooms and cooling systems.

Does it include the cable glands?
Standard units feature dual Pg 13.5 screwed cable entries; however, specific cable glands or seal caps may need to be verified based on your specific enclosure requirements.
