Description
The P70, P72, and P170 Controls for low pressure applications are designed primarily for low pressure cut-out control, pump-down control, 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. Ammonia-compatible models are also available. Controls also are available in several different electrical ratings and switch configurations. The P72 models provide direct control of 208 to 240 volt single-phase motors up to 3 horsepower, and 208 to 220 volt three-phase motors up to 5 horsepower.
Features
All-steel case and cover built to provide long lasting, rugged protection for internal components
Sight-set calibrated pressure adjustment displays a visible pressure scale, fully adjustable through the range without removing the cover (on NEMA 1 enclosure models)
MICRO-SET differential option allows for precise control on critical low pressure applications
Manual reset lockout option provides trip-free low pressure lockout that cannot be overridden or reset until pressure returns to specified level
Limited knob adjustment option restricts control adjustment ranges and deters tampering and over-adjustment
