Johnson Controls P100DA-1 Pressure Control

The Johnson Controls P100DA-1 is a high-performance encapsulated pressure control designed for heavy-duty HVACR applications. Engineered with a direct mount design, this SPST pressure switch features an open on pressure rise action, calibrated to trigger at a 410 PSIG cut-out. Its open construction and 120/240 Vac contact ratings make it a versatile choice for protecting refrigeration compressors and condenser fan cycling systems against extreme high-pressure conditions. The integrated lockout manual reset ensures that the system remains offline after a high-pressure event, requiring a technician's inspection before the manual reset pressure switch can be engaged. Built with a snap-acting diaphragm, the P100DA-1 provides repeatable and vibration-resistant operation, eliminating the contact chatter common in lower-grade pressure limiting devices. This OEM high pressure control is compatible with all common non-corrosive refrigerants, including R-410A and R-22, and features a 1/4 in. SAE female flare with a built-in Schrader valve depressor for fast, reliable installation on standard service ports.

• High-Pressure Protection: Reliable 410 PSIG open-on-rise setpoint prevents compressor damage during system failures.
• Safety First: The trip-free manual reset prevents the contacts from being overridden while the reset button is depressed, ensuring true manual intervention.
• Compact Direct Mount: Lightweight design allows for direct installation onto 1/4-inch flare pressure taps, reducing the need for additional mounting brackets and capillary tubes.
• Technical Durability: Encapsulated construction protects internal snap-action components from dust and moisture, extending service life in demanding environments.
• Universal Compatibility: Rated for 120V and 240V service with a pilot duty rating of 375 VA, suitable for a wide range of commercial refrigeration equipment.

What is the reset logic for the P100DA-1?
This model is a manual reset high pressure control. Once the system pressure exceeds 410 PSIG, the internal contacts open and lock. The control will not close the circuit until the pressure drops approximately 125 PSI below the cutout point and the reset button is manually pressed.

Can this be used with R-410A systems?
Yes, the P100DA-1 is designed for high-pressure refrigerants and is frequently used in R-410A high pressure cutout applications where the maximum system pressure does not exceed 750 PSIG.

Does the P100DA-1 require a separate mounting bracket?
No, its direct mount encapsulated design is specifically engineered to be supported by the 1/4 in. SAE female flare connection directly on the refrigeration piping.
