Description
The Johnson Controls P100CP-1C Pressure Switch Sensor Low Cut-In 400 PSI is a fixed setpoint control used to monitor and regulate refrigerant or air pressure in a system. It operates through a diaphragm-based sensing element that triggers a snap-action electrical switch when it rises to 300 PSI and resets automatically when it falls. It is commonly installed in chillers, air conditioning units, and refrigeration circuits to provide high-pressure protection and cycling control. It operates as a safety and control component within the management circuit, ensuring stable and protected compressor operation under varying load conditions in HVAC systems.
