Square D 9013FHG12M1XZ22 Air Compressor Pressure Switch

Square D 9013FHG12M1XZ22 is a Pumptrol air compressor pressure switch that automatically starts and stops the compressor motor to regulate tank pressure. This model uses a single port with side‑wire electrical connections and a 1/4" NPSF female port for straightforward installation on many air compressors. It is rated for a working pressure range of 105–135 psi, with a 105 psi cut‑in (on) and a 135 psi cut‑out (off), helping maintain a stable pressure as the system cycles. Commonly used as a replacement on older Square D equipment, the 9013FHG12M1XZ22 variant fits within the 9013 family footprint and is compatible with equipment that employs this port configuration. Typical installations include workshop or light‑industrial air compressors where pneumatic tools require consistent pressure in the 105–135 psi window. As part of the Square D Pumptrol line from Schneider Electric, this switch delivers mechanical reliability for controlling compressor motors in demanding environments, with a compact form factor and straightforward wiring that suits side‑wire installations.
