Description
The Johnson Controls P72CA-13 is a heavy-duty pressure control designed for reliable refrigeration and HVAC system protection. Featuring a Double-Pole Single-Throw (DPST) switch-only configuration, this control provides simultaneous switching of two circuits in a single action — ideal for applications requiring complete circuit isolation on pressure events.
Housed in a rugged NEMA 1 enclosure, the P72CA-13 is built for general-purpose indoor installations where protection against dust and light debris is required. The 3/4″ conduit opening ensures straightforward wiring integration into standard electrical conduit systems, simplifying installation in commercial and industrial HVAC environments.
This model ships without an adjustment knob, making it well-suited for OEM applications or installations where field adjustment is not required or desired — helping to prevent unauthorized tampering with system pressure setpoints.
