Applications
The P100CP-165 is ideal for use as a high-pressure safety control in refrigeration and air conditioning systems. It protects compressors and refrigerant circuits by interrupting the control circuit when system pressure exceeds the 600 PSIG cut-out threshold, automatically resetting once pressure drops back to 475 PSIG. Suitable for R-410A, R-22, and other high-pressure refrigerant applications where reliable over-pressure protection is required.
