Schneider Electric 9013GHG5J63X Air Compressor Pressure Switch

Schneider Electric's Square D 9013GHG5J63X air compressor pressure switch with a built-in unloader is a Pumptrol control device that automates electrical power to air compressors and water pumps. It switches at a 145–175 psi range and includes an unloader valve to vent residual pressure at shutdown, easing motor restart. The unit is rated for up to 575 VAC and up to 5 HP loads, enabling use in a wide range of workshop and small- to mid-size industrial applications. As part of the 9013GH GHG family, this switch is designed for reliable cycling control where reservoir pressure must be maintained without excessive cycling. Typical applications include controlling air compressors in commercial shops and pump controllers for small water systems, with the adjustable differential letting you tailor the switch points to your system’s needs while the unloader feature reduces start current and wear on the motor.
