Description
The Schneider Electric (Square D) 9013FRG22J19 is a heavy-duty pressure switch engineered for dependable pressure sensing and control in HVAC, pumping, and industrial applications. Part of Square D’s trusted 9013FRG series, this switch features a 22–16 PSI pressure range with a rising-action (RA) configuration, meaning the contacts close on rising pressure. The double-pole single-throw dead band (DPST-DB) contact arrangement provides two normally open (2NO) contacts for versatile circuit control, while the dead band design helps prevent rapid cycling and extends equipment life.
