- SPST (Single-Pole, Single-Throw) switching action — opens on pressure drop
- Open construction for easy field inspection and serviceability
- Automatic reset eliminates the need for manual intervention after pressure recovery
- Designed specifically for condenser fan cycling duty
Electrical & Pressure Specifications
- Contact Voltage Rating: 120/240 Vac
- Switching Action: Opens on pressure drop (SPST)
- Open Set Point: 150 PSIG
- Close Set Point: 225 PSIG
- Reset Type: Automatic
Application
The P100AP-3 is purpose-built for condenser fan cycling control in commercial refrigeration and HVAC systems. By opening the circuit at 150 PSIG and closing at 225 PSIG, it efficiently manages head pressure to optimize system efficiency, protect compressors, and extend equipment life. Its direct-mount design reduces installation complexity, while the encapsulated housing ensures long-term reliability in outdoor or harsh-environment installations.
