Danfoss 061F8490 Pressure Control

The Danfoss 061F8490 is a heavy-duty ACB cartridge pressure switch engineered for precision high-pressure monitoring in commercial refrigeration and HVAC systems. This SPST (Normally Open) pressure control features a 1/4" female flare connection with a built-in depressor pin, allowing for direct mounting on system schrader valves without the need for additional capillary tubes. Designed for high-side protection or fan cycling applications, the 061F8490 provides a factory-set 160 psi (11 bar) cut-in and a 123 psi (8.5 bar) cut-out. With a max working pressure of 653 psi (45 bar) and an IP65-rated enclosure, this Danfoss pressure switch maintains reliable operation in high-vibration and harsh ambient environments ranging from -20°F to 185°F. Its broad refrigerant compatibility includes R410A, R404A, R134a, and R22, making it a versatile component for technicians maintaining diverse equipment fleets.

• Automatic Reset Function: Ensures seamless system recovery after pressure stabilization without manual intervention.
• Durable Construction: Features a 1.5-meter AWG18 cable and 2900 psi burst pressure capacity for maximum field reliability.
• Compact Cartridge Design: Small footprint allows for installation in tight mechanical compartments where traditional switches won't fit.
• High Electrical Capacity: Rated for 6 A at 250 V AC, suitable for direct control of contactors or high-current alarm circuits.
• Universal Compatibility: Validated for use with modern HFC and HCFC refrigerants, including those with oil-free requirements.

Is the 061F8490 compatible with R410A systems?
Yes, its 653 psi maximum working pressure and materials of construction are fully rated for R410A high-pressure applications.

What is the contact orientation for this switch?
This is an SPST (Single Pole Single Throw) switch with a Normally Open (NO) contact function that closes on rising pressure.

Does this require a mounting bracket?
No, the 1/4" female flare connection is designed for direct mounting, though it should be oriented within ±45° of vertical for optimal performance.
