Johnson Controls P100AC-1 Pressure Control

The Johnson Controls P100AC-1 is a heavy-duty, direct-mount encapsulated pressure control engineered for low-pressure cut-out applications in HVACR systems. Designed as a reliable SPST open low switch, this component features an automatic reset mechanism that triggers an open circuit at 5 PSIG and closes at 20 PSIG. The open construction design facilitates rapid integration into existing manifolds, while the included conduit clamp ensures secure electrical terminations for 120/240 Vac contact ratings. Built to withstand the rigors of commercial refrigeration, this low pressure switch serves as the validated direct replacement for 061F7520 and CNT0508. Contractors utilizing the P100AC-1 benefit from its compact footprint and precise factory-set calibration, which eliminates the need for field adjustments during critical maintenance or system builds. Its hermetically sealed sensing element provides consistent performance across various HVAC pressure control environments, ensuring long-term system protection against low-side pressure drops.

• Precise Setpoints: Pre-calibrated to open at 5 PSIG and close at 20 PSIG for accurate low-pressure monitoring.
• Broad Compatibility: Engineered as a high-performance cross-reference for Danfoss 061F7520 and Trane CNT0508 components.
• Durable Construction: Encapsulated design protects internal switch contacts from environmental contaminants and vibration.
• Streamlined Installation: Direct mount capability and included conduit clamp reduce labor time during field replacements.
• Automatic Reset: Simplifies system recovery by restoring the circuit once the rising pressure reaches the 20 PSIG differential threshold.

Common HVACR Technical Questions

What is the maximum electrical load for the P100AC-1?
This control is rated for standard pilot duty and motor loads at 120/240 Vac, making it suitable for most commercial condensing unit control circuits.

Can this switch be used with all common refrigerants?
The Johnson Controls P100 series is compatible with non-corrosive refrigerants including R-22, R-134a, R-404A, and R-410A, provided the system operating pressures align with the 5/20 PSIG setpoints.

Does the P100AC-1 require additional mounting brackets?
No, this model is a direct-mount encapsulated control designed to thread directly onto a 1/4 inch SAE female flare fitting with a built-in depressor pin.
