Description
The Siemens QPH32.020M00 is a manual reset (M/R) high pressure switch engineered for combustion control applications. With a sensing range of 2–20 inches water column (“wc), this switch provides dependable overpressure detection and safety shutoff in commercial and industrial burner systems. The manual reset design ensures that once a high-pressure fault condition is detected, the system cannot automatically restart — requiring deliberate operator intervention before resuming operation, adding a critical layer of safety to combustion equipment.
