This Burnham Commercial pressure switch is a safety device designed to monitor and regulate the gas pressure in commercial heating systems. It operates by opening or closing an electrical circuit when the gas pressure exceeds or falls below the preset limits, thus preventing potential damage or hazards. The product features a high-pressure limit of 3 to 21 inches of water column (in WC), ensuring a wide range of operational flexibility. It has a manual reset option, allowing users to manually restart the system after a shutdown due to high gas pressure. The switch is designed for natural gas, liquefied petroleum (LP) gas, and air. Its robust construction ensures durability and reliability in demanding commercial environments.
