QPB32.060A00 Siemens Gas Pressure Switch

Overview

The Siemens QPB32.060A00 is a high-performance gas pressure switch designed for the precise monitoring of gas or air pressures in commercial and industrial combustion systems. Part of the Siemens QPx32 series, this automatic reset switch is engineered to detect both high and low pressure conditions. Its rugged construction and NEMA 4 rating make it suitable for challenging environments, including outdoor installations, ensuring the safe and reliable operation of burners, boilers, and furnaces by preventing hazardous conditions.

Features

• Automatic reset mechanism returns the switch to active monitoring once pressure returns to the setpoint
• Versatile compatibility with natural gas, propane, butane, hydrogen, biogas, and air
• Ventless operation up to 7 psig, eliminating the need for external vent piping in many applications
• NEMA 4 rated enclosure provides superior protection against dust, water, and outdoor exposure
• Integrated side test connection allows for easy attachment of a manometer or pressure gauge during commissioning
• Compact design facilitates mounting to 1/2 inch flexible conduit fittings without the need for additional adapters
