SPST PRESSURE CONTROL; 20"/100# DIFF 7/50# ADJ CONN 5 OPEN 60+/-1# CLOSE 40+/-1#

Application

• P70, P72, and P170 controls for low pressure applications are designed primarily to provide low-side pressure control on commercial refrigeration and air conditioning applications.
• P70 and P170 models are also available with SPST Open-high switch action, and are typically used for capacity control. Models with Single-Pole Double-Throw (SPDT) or 4-wire, 2-circuit switch action allow users to install alarm devices or other control circuits.
•  P72 models have a Double-Pole Single-Throw (DPST) switch with load-carrying contacts that can provide direct control of 208-240 V single-phase motors up to 3 hp, and 208-220 V 3-phase motors up to 5 hp. Refer to Table 8.

These controls are available in several pressure ranges and are compatible with most common refrigerants. They may also be used on air, water, and other non-corrosive fluid applications. Ammonia compatible models are also available.
