Description
The Johnson Controls P100DA-86 is a commercial-grade encapsulated pressure control engineered for reliable high-side pressure protection in refrigeration and HVAC systems. Featuring a direct-mount design and open construction, this control is built for straightforward field installation and long-term serviceability.
Key Features
- Encapsulated design protects internal components from moisture and contaminants
- Direct mount configuration for simplified installation without additional brackets or adapters
- SPST (Single-Pole, Single-Throw) switching action for clean, reliable circuit control
- Opens on pressure rise — provides automatic high-pressure cutout protection
- Open construction allows for easy inspection and field servicing
- Lockout manual reset on close — requires manual intervention after a high-pressure trip, preventing automatic restart and protecting equipment
Electrical & Pressure Specifications
- Contact Voltage Rating: 120/240 Vac
- Switching Action: Open on Pressure Rise
- Open Set Point: 575 PSIG
- Reset Type: Lockout Manual Reset on Close
- Mounting: Direct Mount
- Construction: Open
Applications
- High-pressure cutout protection on refrigeration compressors
- Commercial HVAC condensing units
- Chiller and refrigeration system high-side pressure monitoring
- Any application requiring manual reset after a high-pressure safety trip
The lockout manual reset feature is a critical safety function — once the control opens due to a pressure rise above 575 PSIG, the system cannot automatically restart. A technician must manually reset the control, ensuring the root cause of the high-pressure condition is investigated and resolved before the system is returned to service. This makes the P100DA-86 an ideal choice for protecting compressors and refrigeration equipment from repeat high-pressure damage.
