P170CA-400C Johnson Controls Pressure Control

Part number P170CA-400C from Johnson Controls, listed in Power Supplies & Transformers. KKM Solutions quotes this part with pricing and availability confirmed per order.

Overview The Johnson Controls P170CA-400C is a high-quality electromechanical single pressure control designed for high-pressure cutout protection in commercial and industrial refrigeration and air conditioning systems. It features a single-pole, single-throw (SPST) open-high switch action that opens on rising pressure to protect compressors and system components from dangerous over-pressure conditions. Equipped with an automatic reset mechanism, the control restores operation once the pressure drops back down to the safe, predefined level. Features All-steel case and cover provides rugged, long-lasting protection for internal components Sight-Set calibrated pressure adjustment allows for a highly visible scale that is fully adjustable without removing the cover Single-pole, single-throw (SPST) open-high switching action provides reliable high-side system protection Automatic reset action seamlessly restores operations when pressure returns to normal levels Generous electrical rating compatibility allows for versatile use across standard commercial power supplies UL listed as a refrigeration pressure limiting control Specifications Brand: Johnson Controls Model: P170CA-400C Switch Type: SPST (Single-Pole, Single-Throw) Switch Action: Open-High (Opens on rising pressure) Reset Type: Automatic Reset Pressure Range: 200 to 610 psi (1,379 to 4,206 kPa) Pressure Differential: 60 to 150 psi (414 to 1,034 kPa) Pressure Connection: 1/4 inch External Flare Connector Maximum Working Pressure: 690 psig (4,757 kPa) Enclosure Rating: NEMA 1 Electrical Ratings: 120/208/240 VAC compatibility Applications The P170CA-400C is primarily utilized for high-pressure cutout control and limit protection in commercial air conditioning and refrigeration systems. It is engineered for use with non-corrosive high-pressure refrigerants, such as R410A, helping to maintain safe high-side limits, maximize system reliability, extend compressor equipment life, and prevent costly downtime.
