Modine 5H0722750001 0.78"WC SPST Pressure Switch

The Modine 5H0722750001 is a Single Pole Single Throw (SPST) pressure switch designed for use in Modine heating equipment and HVAC systems. This switch is calibrated to actuate at 0.78 inches water column ("WC), making it ideal for monitoring air pressure in combustion air proving applications, furnace draft safeguards, and ventilation systems.

Key Features:

• SPST (Single Pole Single Throw) switching configuration for simple on/off control
• 0.78"WC pressure setpoint for precise air pressure monitoring
• Direct replacement for Modine heating equipment
• Reliable pressure sensing for safety and operational control
• Designed for low-pressure air applications in commercial and industrial settings

This pressure switch serves as a critical safety component in gas-fired heating systems, ensuring proper airflow and pressure conditions before allowing equipment operation. The 0.78 inch water column setpoint makes it suitable for applications requiring sensitive pressure detection in duct systems, combustion air proving, and pressure differential monitoring.
