Description
P170 Controls for high pressure applications are designed primarily for high pressure cut-out control, head-pressure control, and condenser fan cycling control on commercial refrigeration and air conditioning applications.
- all-steel case and cover provides 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)
- manual reset lockout option provides trip-free lockout that cannot be overridden or reset until pressure returns to specified level
- variety of available pressure connection styles allows greater flexibility when mounting control and adapting pressure connections to field application requirements
- P170 Model with single-pole, single-throw (SPST) Open High switch action are the most popular models, and are typically used for high-pressure cutout
- P170A model is available with SPST Open Low switch action, and typically are used for condenser fan cycling control
- P170 model with single-pole, double-throw (SPDT), or four-wire, two-circuit switch action allow users to install alarm devices or other control circuits
