The Johnson Controls P100AC-2 is an encapsulated, direct-mount pressure control designed for reliable refrigeration and HVAC system protection. Featuring an open-construction housing with a Single-Pole Single-Throw (SPST) switching configuration, this control opens on a pressure drop (Open Low) to safeguard compressors and refrigeration circuits from low-pressure conditions.
How It Works
The P100AC-2 monitors system pressure and interrupts the circuit when pressure falls to the cut-out set point, then automatically resets and re-closes the circuit once pressure recovers to the cut-in set point — no manual intervention required.
Key Features
- Encapsulated pressure control with open construction housing
- Direct-mount design for simplified installation
- SPST switching action — Opens on Low pressure (Open Low)
- Opens at 15 PSIG (cut-out set point)
- Closes at 30 PSIG (cut-in set point)
- 120/240 Vac contact ratings for broad electrical compatibility
- Automatic reset — no manual reset required after pressure recovery
- Includes conduit clamp for secure wiring management
