Modine 5H0794410009 0.80"WC SPST Pressure Switch

The Modine 5H0794410009 is a precision SPST (Single Pole Single Throw) pressure switch designed for HVAC and heating equipment applications. This switch is calibrated to actuate at 0.80 inches of water column (WC), making it ideal for monitoring and controlling air pressure in furnaces, unit heaters, and ventilation systems.

Key Features:

• 0.80"WC pressure activation setpoint for reliable operation
• SPST switching configuration for simple on/off control
• Engineered specifically for Modine heating equipment
• Durable construction for long-term reliability in HVAC applications
• Safety control component that ensures proper draft and combustion air pressure

This pressure switch is a critical safety component that monitors air pressure differentials to ensure proper system operation. When pressure reaches the specified threshold, the switch contacts close to signal that adequate airflow is present, allowing the heating system to operate safely.
