Description
The Johnson Controls P170DA-1 is a high pressure control designed for use with non-corrosive refrigerants in commercial and industrial HVAC and refrigeration systems. Featuring a Single-Pole Single-Throw (SPST) switching action that opens on a rise in pressure, this all-range control provides reliable high-side pressure protection across a broad operating range of 50 PSIG to 500 PSIG.
Equipped with a manual reset lockout, the P170DA-1 requires a deliberate operator reset before the system can restart after a high-pressure trip event — helping protect compressors and system components from repeated fault cycling. The 1/4″ male flare connector ensures straightforward field installation with standard refrigeration fittings.
