Danfoss 060-205991 Pressure Control

The Danfoss 060-205991 KP1 Pressure Control is a heavy-duty single pressure switch designed for regulating and monitoring commercial refrigeration and air conditioning systems. This specific model serves as the direct updated version for 060-205966, ensuring seamless integration into existing HVACR control systems. Engineered for low-pressure cut-out applications, it features an adjustable range of 10 to 58 psi (0.7 to 4 bar) with a fixed differential of 10 psi (0.7 bar). The unit is equipped with a 36-inch capillary tube and a 1/4-inch flare nut, providing flexibility for manifold or remote mounting. Its SPDT contact system (Single Pole Double Throw) facilitates reliable compressor motor control or alarm activation. Built with a robust bellows system, the Danfoss KP1 handles high vibration environments without contact chatter, ensuring precise pressure regulation for R22, R134a, R404A, and R507A refrigerants.

Key Benefits for Technicians

• Direct Replacement: Purpose-built to replace the legacy 060-205966 model with identical footprint and electrical ratings.
• High Vibration Resistance: The "snap-action" contact system reduces wear and prevents arcing when used near reciprocating compressors.
• Flexible Installation: Features a 36-inch capillary tube to bypass tight space constraints in the mechanical room.
• Ultra-Fast Response: Near-instantaneous switching ensures the low-pressure safety cut-out protects the compressor against loss of charge.
• Serviceability: Front-facing adjustment screws allow for easy setpoint calibration while the unit is mounted.

Common Questions and Technical Support

What is the maximum working pressure for this control?
The Danfoss 060-205991 is rated for a Maximum Working Pressure (MWP) of 245 psig, making it suitable for a wide range of low-side refrigerant monitoring tasks.

Can this switch be used for high-pressure cut-out?
No, this specific KP1 model is designed for low-pressure applications. For discharge-side protection, a KP5 or KP15 high-pressure control should be utilized.

Does this unit feature an automatic or manual reset?
The 060-205991 is an automatic reset pressure switch, meaning it will re-close the circuit once the suction pressure rises above the setpoint plus the differential.
