Square D 9013GHG1S8J54 Pressure Switch 110-125 Psig

Product Description

The SQUARE D 9013GHG1S8J54 is a DPST pressure switch rated for 110 to 125 psig, designed for use in electrically driven systems where automatic pressure-based control is required. It operates at up to 575 VAC and features an adjustable differential pressure range of 20 to 40 psi, giving technicians flexibility to fine-tune cut-in and cut-out setpoints in the field. The switch connects via a 0.13 inch NPSF port and uses screw terminals for wiring. Weighing 1.88 pounds, it carries NEMA 1 enclosure protection. Licensed electricians and mechanical contractors are the typical installers for this type of pressure control device.

This pressure switch is intended for air compressor pressure control and electrically driven water pump applications. It is suited for residential and light commercial installations where a NEMA 1-rated enclosure is appropriate, meaning the installation environment must be dry and indoors. The adjustable differential feature makes it adaptable to system-specific pressure requirements within the rated range, reducing the need for multiple fixed-differential SKUs across a service fleet.

Key Features

• Pressure range: 110 to 125 psig with DPST contact form for simultaneous line switching
• Adjustable differential pressure: 20 psi minimum, 40 psi maximum
• 575 VAC rated for compatibility with higher-voltage single-phase and three-phase supply circuits
• 0.13 inch NPSF pressure port connection for direct pipe-mount installation
• Screw terminal wiring for secure, code-compliant conductor termination
• NEMA 1 enclosure rating for indoor dry-location service

Compatibility

Designed for use with air compressors and electrically driven water pumps requiring automatic pressure switching in the 110 to 125 psig operating range.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements. De-energize and lock out the circuit and relieve system pressure before removing or installing this switch. The NEMA 1 rating requires a dry, indoor mounting location — do not install in wet, outdoor, or wash-down environments. Verify that supply voltage and conductor sizing are consistent with the 575 VAC rating and applicable local codes before energizing.
