Johnson Controls P72CA-13 Pressure Control

The Johnson Controls P72CA-13 Pressure Control is a heavy-duty high pressure cutout designed for professionals managing commercial refrigeration and HVAC systems. As a DPST pressure switch, this unit provides direct control for 208-240V single-phase motors up to 3 hp and 208-220V 3-phase motors up to 5 hp, making it an essential component for condenser fan cycling and high-limit protection. Housed in a rugged NEMA 1 enclosure with an all-steel case, it features a 3/4" conduit opening for simplified field wiring and is compatible with all non-corrosive refrigerants. This specific model utilizes a bellows sensing element and is factory-set without an external adjustment knob to prevent unauthorized tampering with system setpoints. Whether you are performing a Penn pressure control replacement or installing a new head pressure management circuit, the P72CA-13 ensures reliable circuit interruption when system pressures exceed safe operating limits.

• High-Capacity Switching: The Double-Pole Single-Throw (DPST) configuration allows for direct motor control without needing additional contactors in many applications.
• Enhanced Durability: Built with an all-steel case and cover to withstand demanding mechanical room environments.
• Tamper-Resistant Design: No adjustment knob ensures that critical safety and high pressure limit settings remain exactly where the technician set them.
• Standardized Installation: Features a 3/4 inch conduit opening and universal mounting compatibility for seamless integration into existing HVACR control systems.

• What is the switch action for the P72CA-13? This model features an "Open on Rise" action, typically used as a high-pressure safety cutout to protect the compressor.
• Is this control compatible with R-410A? Yes, the P72CA-13 is compatible with most common non-corrosive refrigerants used in modern commercial systems.
• Can this unit be mounted outdoors? The standard NEMA 1 enclosure is designed for indoor protection. For outdoor applications, a NEMA 3R housing would be required.
