Danfoss 017D002166 Pressure Control

The Danfoss 017D002166 (Type RT260A) is a mission-critical differential pressure control designed for demanding industrial refrigeration and HVACR applications. Built for precision monitoring of pressure discrepancies, this switch operates within a 0.5 to 4 bar (7.3 to 58 psi) regulation range, making it ideal for monitoring oil pressure in compressors or pump flows in plant rooms. It features a robust IP66 enclosure, ensuring maximum reliability in environments where moisture and dust ingress are concerns. The high-performance SPDT contact system provides flexible wiring options for both alarm and cut-off functions, supported by a fixed 0.3 bar contact differential. Compatible with ammonia (NH3) and fluorinated refrigerants, this Danfoss RT260A pressure switch utilizes 3/8-inch G-type connections and a mechanical bellows design that delivers superior repeatability. For technicians performing replacements or new installs, the 017D002166 provides the stability needed for safety-critical neutral zone regulation and heavy-duty industrial cycling.

• Versatile Media Compatibility: Engineered for use with ammonia (NH3), water, steam, and most common refrigerants.
• Extreme Durability: Rated for a maximum working pressure of 22 bar (319 psig) with an ambient temperature range of -58°F to 158°F.
• Flexible Signal Handling: The single-pole changeover (SPDT) contact supports AC and DC current for diverse control circuit integration.
• Weatherproof Protection: Features an IP66-rated housing, preventing operational failure in harsh, wash-down, or marine environments.
• Automatic Reset: Simplifies system recovery with a reliable auto-reset function following pressure restoration.

What is the maximum test pressure for the Danfoss 017D002166?
