The Modine 5H0735910005 is a single pole single throw (SPST) pressure switch designed for HVAC and heating equipment applications. This pressure-activated switch operates at 1.10 inches water column ("WC), making it ideal for monitoring air pressure in furnaces, unit heaters, and other combustion appliances.

Key Features:

• SPST (Single Pole Single Throw) configuration for simple on/off switching
• 1.10"WC pressure setpoint for reliable pressure sensing
• Designed for use in Modine heating equipment and compatible HVAC systems
• Ensures proper air pressure before allowing equipment operation
• Safety component that helps prevent unsafe operating conditions

This pressure switch is a critical safety component that monitors air pressure in heating systems. When proper pressure is detected, the switch closes to allow the heating sequence to continue. If pressure falls below the setpoint, the switch opens to prevent unsafe operation. Genuine Modine replacement part ensures proper fit and reliable performance.
