MARS 43306 SPST Close on Rise Fan Cycling Pressure Switch 275 PSI-CL, 210 PSI-OP

The MARS 43306 SPST Fan Cycling Pressure Switch functions as a dependable pressure control equipment that operates specifically, within HVAC systems for air conditioning and refrigeration needs. This switch activates at 275 PSI but deactivates at 210 PSI while closing on pressure rise to achieve efficient fan cycling for system operation. This part operates with electrical systems ranging from 24-250V which enables it to work with multiple setups. It protects compressors and controls condenser coil temperatures through system pressure-based fan regulation. This equipment helps cooling systems run more efficiently because it directs fans for cooling only when required to prevent overheating and extends component longevity.
