Modine 5H0780340010 Pressure Switch 30067439-890 This staged activation prevents nuisance

This staged activation prevents nuisance tripping of the main circuit breaker by managing the inrush current during the initial startup phase

Most trips are caused by restricted airflow

the Raypak 006535F Flame Sensor is often the first component to inspect

making it suitable for high-pressure refrigerants and hot water applications
