Ranco MPH-7107-70 Mini Pressure High Side Limit Control Switch is a compact, SPST high-side protection device for refrigeration and HVAC systems, featuring a 1/4" NPT process connection and an 18-inch lead wire assembly. It trips at 400 psi (cut-out) and resets at 300 psi (cut-in), providing a fixed differential to guard equipment from overpressure. Typical applications include protecting compressors, condensers, and refrigerant circuits in commercial refrigeration and air conditioning installations, where reliable high-side limit control is critical.
