The P77 Series Controls for high pressure Applications are designed primarily for high pressure cut-out control, pump-down control, condenser fan cycling, and capacity control on commercial refrigeration and air-conditioning applications.
These controls are available in several pressure ranges and are compatible with most common refrigerants. They may also be used on other non-corrosive fluid applications. Controls also are available in several different electrical ratings and Single-Pole, Double-Throw (SPDT) switch configurations.
