Schneider Electric 9013FHG19M1XZ22 Pressure Switch

Schneider Electric's Square D 9013FHG19M1XZ22 Pressure Switch is a Pumptrol compressor pressure switch with an ON-OFF lever and a single pressure port, built to automate air compressor control. It belongs to the Class 9013 Type FHG family, and the M1 suffix indicates a maintained manual cut-out lever that must be manually reset to restart after shutdown. This 9013FHG19 configuration is designed for indoor use in NEMA Type 1, IP20 environments and offers an adjustable cut-out range from about 70 to 150 psi (4.8–10.3 bar) with a fixed differential, enabling reliable cycling of the compressor as system pressure changes. The unit is compact, weighing approximately 0.75 lb (0.34 kg), making it suitable for panel mounting in tight spaces. Used to protect pumps and piping from overpressure, it switches the compressor motor on and off in response to sensed pressure, a common choice for commercial and industrial air‑compression systems where a simple, field‑serviceable pressure switch is required.
