Description
The Johnson Controls P100CP-2 is a direct-mount encapsulated pressure control engineered for reliable high-side pressure protection in commercial and industrial HVAC and refrigeration systems. Featuring open-on-pressure-rise switching action, this SPST control automatically interrupts the circuit when system pressure reaches the set open point, then resets automatically once pressure drops to the close point — eliminating the need for manual intervention and reducing system downtime.
Key Features
- Encapsulated construction protects internal components from moisture, dust, and contaminants for long service life
- Direct-mount design simplifies installation directly to system refrigerant lines or pressure ports
- SPST (Single-Pole, Single-Throw) switching for straightforward circuit control
- Open-on-pressure-rise action provides reliable high-pressure cutout protection
- Automatic reset restores operation once pressure falls back to the close set point — no manual reset required
- Open construction allows for easy field inspection and wiring access
