Danfoss 017-529566 Pressure Switch

The Danfoss RT117 pressure switch (017-529566) is a heavy-duty sensing solution engineered for high-pressure industrial refrigeration and process control applications. Designed to monitor and regulate pressure in systems utilizing R22, R134a, R404A, R407C, and R507A refrigerants, this unit features a robust SPDT (Single Pole Double Throw) contact system with a rated switching capacity for motors up to 2 kW. The RT117 offers a dedicated pressure range of 10 to 30 bar (145 to 435 psi) with an adjustable differential between 0.6 and 3.5 bar, providing precise mechanical control for high-side compressor protection or liquid line monitoring. Built to withstand harsh environments, the IP66-rated enclosure houses a reliable bellows system designed for high cycle life and vibration resistance. Proper installation requires 1/4-inch flare or G 3/8 A pressure connections, ensuring a leak-proof interface with the main line. This switch is the industry standard for contractors requiring durable HVACR pressure controls that maintain setpoint stability under fluctuating thermal loads.

• High-Pressure Capability: Specifically designed for R410A and high-pressure ammonia or fluorinated refrigerant circuits.
• Modular Integration: Standardized mounting holes and wiring terminals facilitate rapid replacement of legacy commercial pressure controls.
• Mechanical Reliability: Bellows-actuated mechanism ensures accurate trip and reset points without the drift common in lower-tier electronic sensors.
• Fail-Safe Switching: High-load SPDT contacts allow for both high-limit cut-out and low-side alarm signaling simultaneously.

What is the maximum working pressure for the RT117?
The Danfoss 017-529566 is rated for a maximum working pressure (MWP) of 42 bar, making it suitable for high-end industrial pressure testing and operation.

Does this switch support manual reset?
This specific model is an automatic reset pressure switch. Once the pressure falls below the setpoint minus the differential, the contacts automatically return to their normal state.

What is the ambient temperature range for installation?
This pressure controller is designed to operate reliably in ambient temperatures ranging from -50°C to +70°C, suitable for outdoor compressor racks or mechanical rooms.
