Schneider Electric (Square D) 9013FHG9J27 40/100 PSI Pressure Switch Open Hi 1/4″

Description

Product Overview

The Schneider Electric (Square D) 9013FHG9J27 is a heavy-duty electromechanical pressure switch engineered for reliable pressure sensing and control in HVAC, compressor, pump, and industrial fluid-system applications. With a 40 PSI cut-in and 100 PSI cut-out pressure range and an open-high switching action, this switch opens its contacts as system pressure rises to the cut-out setpoint — providing precise, dependable protection and control for a wide range of mechanical systems.

Key Features

• Cut-In Pressure: 40 PSI — contacts close as pressure rises to this point
• Cut-Out Pressure: 100 PSI — contacts open as pressure rises to this point
• Open-High (Open Hi) switching action: switch opens on pressure rise
• 1/4″ pressure port connection for easy integration into standard piping or tubing systems
• Rugged Square D construction for long service life in demanding environments
• Suitable for compressor, pump, HVAC, and general industrial pressure control applications

Application

The 9013FHG9J27 is ideal for use in air compressor systems, hydronic and steam systems, pump protection circuits, and other HVAC or industrial processes where automatic pressure-based switching is required. The open-high configuration is commonly used for high-pressure cutout protection, shutting down equipment when pressure exceeds the safe operating threshold.
