Schneider Electric's Square D 9013-ASG8-S6 pressure switch is a Pumptrol electromechanical device that automatically starts and stops a pumping system in response to changing system pressure. For this ASG8-S6 variant, the unit switches at about 80 psi (closing the contacts) and 100 psi (opening the contacts). This model is part of the 9013 series, commonly used for commercial and residential pump controls such as well pumps, booster pumps, and recirculation systems. The 9013 family provides automatic pressure control in pumping circuits and is integrated within Square D's Pumptrol lineup for reliable pump operation.
