Danfoss 060-200391 Pressure Control

The Danfoss 060-200391 KP7W Pressure Control is a heavy-duty high pressure switch engineered for superior protection in commercial refrigeration and HVAC systems. Professionals recognizing the KP7W series will find this model a direct, dropping replacement for legacy units 060-519066 and 060-200366. It operates across a regulation range of 116 to 464 psig (8 to 32 bar) with a 1/4 inch male flare connection (DIN 8906), ensuring a high-integrity seal in high-vibration environments. The SPDT contact function and auto reset mechanism provide autonomous system safety, while the adjustable differential (58 to 145 psi) allows technicians to fine-tune cut-out and cut-in points for precision cycling. Constructed with a responsive bellows pressure sensing element, it is compatible with a broad range of HCFC and non-flammable HFC refrigerants, including R404A, R134a, R22, and R407C. This IP30-rated control is the industry standard for preventing compressor damage due to excessive discharge pressure.

Key Benefits for Contractors

• Direct Compatibility: Seamlessly replaces 060-519066 and 060-200366 models, reducing downtime during field service.
• High Load Capacity: Features a 16A resistive single-phase rating and 16 FLA at 120VAC, handling demanding electrical loads without external relays.
• Broad Refrigerant Versatility: Qualified for Fluid Group 1 and Group 2, making it a "truck-stock" essential for R134a, R404A, R407A, R407C, and R407F systems.
• Enhanced Durability: Tested for stable switching and long service life with a burst pressure of 140 bar, exceeding standard HVAC safety switch requirements.
• Precise Calibration: The adjustable differential provides 4 to 10 bar of flexibility to prevent short-cycling in complex high-pressure protection applications.

Common Questions

Is the Danfoss KP7W an automatic or manual reset switch?
The 060-200391 is an auto reset control. It will automatically re-engage the circuit once the system pressure falls below the differential setting relative to the cut-out point.

What is the maximum working pressure for this unit?
This high pressure control is rated for a Maximum Working Pressure (MWP) of 510 psig (35 bar), making it suitable for modern high-pressure refrigerant cycles.

Can this be used with ammonia (R717)?
No, the KP7W series is designed for HCFC and HFC refrigerants. For ammonia applications, a stainless steel bellows unit such as the Danfoss KP-A series is required.
