Danfoss 017-523766 Pressure Switch

The Danfoss 017-523766 RT200 Pressure Switch is a heavy-duty industrial pressure control engineered for precision in demanding HVACR and steam plant environments. Built with a regulation range of 0.2 to 6 bar (2.9 to 87 psig) and an adjustable differential of 0.25 to 1.2 bar, this RT series switch provides the reliability needed for neutral gases and non-corrosive liquids. The unit features a Single Pole Double Throw (SPDT) contact system, allowing for flexible wiring as a high-pressure cutout or low-pressure controller. Its IP66-rated enclosure ensures maximum resistance to dust and moisture, making it ideal for engine rooms and plant floors. Equipped with a G 3/8 male pressure connection and an automatic reset function, this Danfoss pressure switch streamlines compressor control and pump protection while maintaining high electrical load capacity with AC15 3A 400V ratings.

Key Benefits for Contractors

• Rugged Enclosure: The IP66 rating allows for installation in harsh industrial areas where washdowns or high humidity occur.
• High Load Capacity: Robust SPDT contacts handle up to 10A (AC1), reducing the need for auxiliary relays in many pressure monitoring circuits.
• Wide Media Compatibility: Suitable for use with air, water, and fluorinated refrigerants including R134a, R404A, and R507C.
• Precision Adjustment: Fine-tune your setpoints and differentials easily via the top-mounted mechanical dials for stable HVAC system control.
• Superior Longevity: Designed with a high-strength bellows construction to withstand max working pressures up to 22 bar.

Common Questions

How do I wire the Danfoss RT200 for a low-pressure cutout?
Technicians should use terminals 1 and 2 of the SPDT switch. The circuit will open on falling pressure according to your dial setpoint. For high-pressure applications, use terminals 1 and 4 to open the circuit when pressure exceeds the set limit.

Does this unit require manual resetting after a trip?
No, the 017-523766 is an automatic reset pressure switch. Once the pressure moves past the differential range, the contacts will return to their default state without field intervention.

What is the connection type for this model?
This specific RT200 model utilizes a G 3/8 male threaded connection (ISO 228-1), which is standard for most industrial Danfoss manifold blocks and piping systems.
