Johnson Controls P47AA-13 Pressure Switch 0-150 PSI SPST Open-High

The Johnson Controls P47AA-13 Pressure Switch is an essential element in HVAC systems which controls the high pressure with greater accuracy. It employs a single-pole single-throw contact kind and operates at a 0 to 150 psi pressure level. It works by allowing circuits when the pressure ranges are higher than a standard value. This is precaution from the effects that may result from over-pressure not only on the compressor, refrigeration systems and hydraulic applications. The installation process normally ensures power output maximizing and safety through avoiding overpressure instances and total un-productivity periods.
