Modine 5H0794410002 Pressure Switch The MARS 19165 Potential Relay

The MARS 19165 Potential Relay is a high-performance motor starting component engineered for capacitor-start

Integrating this 10 SCFM filter into your routine maintenance schedule prevents the premature wear of sensitive pneumatic valves and actuators by providing reliable air intake protection

ensuring exact terminal alignment and mounting footprints

regardless of the number of main power poles

Standard service protocol suggests removing the actuator from the valve via the set screw for safer bench assembly

Modine 5H0794410002 Pressure Switch The MARS 19165 Potential RelayThe Modine 5H0794410002 Pressure Switch is the current OEM replacement for the legacy 5H79441 2 and is a critical safety component for high efficiency unit heaters. Rated at . 70" WC with an SPST (Single Pole Single Throw) configuration, this switch acts as the primary proof of airflow for the combustion process. It ensures the power exhauster is generating sufficient vacuum before allowing the ignition sequence to proceed, preventing hazardous
