Johnson Controls P100CA-1 Pressure Control

The Johnson Controls P100CA-1 is a professional-grade encapsulated pressure control designed for high-pressure cutout and fan cycling in commercial HVACR systems. Built for direct mount installation, this SPST switch features a fixed, factory-calibrated setpoint that ensures foolproof operation in the field. The heavy-duty snap-acting disc is engineered to open on pressure rise at 400 PSIG and provide an automatic reset when the system pressure drops to 300 PSIG. Its open construction and compact, lightweight design allow for 1/4 inch SAE female flare mounting directly to the refrigeration piping, effectively eliminating the need for additional capillary tubing or mounting brackets. This unit is compatible with all non-corrosive refrigerants and supports 120/240 Vac contact ratings, making it a versatile choice for condensers, ice machines, and food service equipment. By utilizing a 48-inch lead wire connection, the P100CA-1 pressure switch provides a reliable high-limit safety solution that maintains precise, repeatable performance under diverse ambient conditions.

• Direct-Mount Versatility: The 1/4 inch female flare fitting includes a built-in Schrader type depressor, allowing for quick installation directly on the service port.
• Tamper-Proof Reliability: Factory-calibrated at 400 PSIG open / 300 PSIG close to ensure critical safety limits are never adjusted or bypassed in the field.
• Environmental Protection: The encapsulated, dust-tight switch housing protects internal contacts from oil, moisture, and debris commonly found in mechanical rooms.
• Broad Compatibility: Rated for both 120V and 240V pilot duty (375 VA), suitable for various motor and sequencing applications in refrigeration.

Does this control require a mounting bracket?
No, the P100CA-1 is designed for direct mounting via its 1/4 inch pressure port, reducing installation time and eliminating vibration issues associated with capillary lines.

Can I use this for low-pressure cutout?
This specific model is calibrated for high pressure cutout (opens at 400 PSIG). For low-pressure applications, you should select a P100 series model with "open on pressure drop" logic.

Is the reset manual or automatic?
This is an automatic reset control. Once the system pressure falls below the 300 PSIG deactuation point, the contacts will automatically close to resume operation.
