Johnson Controls P100DA-35 Pressure Control

The Johnson Controls P100DA-35 is a heavy-duty encapsulated pressure control engineered for high-pressure cut-out applications in commercial HVACR systems. This direct mount pressure switch features an SPST contact configuration designed to open on pressure rise at 350 PSIG. Built with open construction for versatile integration, the P100DA-35 includes a manual reset lockout mechanism, ensuring the system remains offline until a technician verifies the fault condition. Rated for 120/240 Vac, this control is a drop-in replacement for the P100DA-35C, offering identical performance specifications. The hermetically sealed sensor prevents moisture ingress and vibration-induced fatigue, making it reliable for high-side protection in refrigeration racks and air conditioning units. Its compact profile facilitates installation in tight mechanical headers where larger high pressure cut-out switches cannot fit. For contractors requiring a precise manual reset pressure switch that maintains calibration under extreme cycle counts, this Penn series control provides industrial-grade reliability for refrigeration pressure control requirements.

• Manual Reset Safety: Prevents automatic equipment restarts after a high-pressure event, protecting the compressor from repetitive cycling.
• Direct Mount Interface: Simplifies installation by eliminating the need for additional capillary tubes or mounting brackets.
• Cross-Compatibility: Fully interchangeable with the P100DA-35C for streamlined inventory management.
• Encapsulated Design: The hermetically sealed switch prevents contact contamination from dust, moisture, and debris in mechanical rooms.
• High Electrical Rating: Robust 120/240 Vac contact ratings allow for direct control of motor starters or alarm circuits.

Common Questions

What is the difference between the P100DA-35 and the P100DA-35C?
There is no functional or physical difference between these two models; they are identical components with the same 350 PSIG setpoint and manual reset configuration.

Does this switch require a separate mounting bracket?
No, this is a direct mount control designed to thread directly onto the system fitting, reducing potential leak points associated with capillary lines.

How do I reset the lockout after a pressure trip?
Once the system pressure drops below the reset threshold, the technician must manually depress the reset button on the top of the encapsulated housing to close the SPST circuit.
