Danfoss 060-200491 Pressure Control

The Danfoss 060-200491 Pressure Control is a high-performance KP7B pressure switch designed for critical refrigeration and air conditioning system monitoring. Engineered to provide reliable protection against extreme high-pressure conditions, this unit features a wide regulation range of 115 to 465 PSI with a fixed 58 PSI differential. As the direct successor to the discontinued 060-200466, it offers enhanced mechanical durability and a fail-safe double bellows system, ensuring a high level of system safety during discharge pressure spikes. The 1/4" male flare connection facilitates a secure, standardized fit for most commercial HVACR manifolds.

Built with a single-pole double-throw (SPDT contact function), the 060-200491 provides versatile electrical control for compressor cycling or high-pressure alarm signaling. The manual reset feature ensures that technicians must physically inspect the system before restarting, preventing damage from repeated cycling during a fault. Its compact design and vibration-resistant bellows element make it suitable for heavy-duty applications, maintaining calibration and sensitivity even in high-vibration engine rooms or outdoor condenser units.

Key Benefits

• Precise Overpressure Protection: Maintains a high pressure cut-out range of 115 to 465 PSI to protect compressors and system components.
• Fail-Safe Bellows System: The KP7B series utilizes a double bellows assembly to prevent refrigerant loss even if the primary bellows fails.
• Fast Electrical Response: Features a snap-action SPDT switch that reduces contact wear and ensures consistent electrical performance.
• Industry Standard Compatibility: Replaces the older 060-200466 model seamlessly with the same 1/4 inch male flare mounting footprint.
• Manual Reset Security: Ideal for high pressure safety limits where a controlled system restart is required for safety protocols.

Common Questions

Which refrigerants are compatible with the Danfoss 060-200491?
This pressure control is designed for use with HCFC and non-flammable HFC refrigerants commonly found in commercial cooling systems.

How do I wire the SPDT contact for a high-pressure cutout?
For high-pressure protection, technicians typically wire the compressor contactor through the NC (normally closed) contacts, which open upon reaching the set cut-out pressure.

Is the differential on the KP7B adjustable?
No, the Danfoss 060-200491 features a fixed differential of 58 PSI, specifically calibrated for manual reset safety applications.
