It monitors system pressure and cuts power to the compressor clutch if the pressure gets too low (indicating a refrigerant leak or low charge) or too high (indicating a blockage or overcharge). With a normally open design and a 7/16-20 female thread, it’s a common replacement for many heavy-duty air conditioning systems.
