Square D 9012GRG5 Pressure Switch Spdt 3-150 Psi

Product Description

The SQUARE D 9012GRG5 is an electromechanical pressure and level switch designed for industrial and commercial control applications. It operates on a single-pole double-throw (SPDT) contact form with a fixed differential pressure setting, making it suitable for systems that require reliable, repeatable pressure-actuated switching. The switch covers a pressure range of 3 to 150 psi and carries a NEMA 1 enclosure rating. Electrical ratings include 120 VAC at 6 amps, 240 VAC at 3 amps, 125 VDC at 0.22 amps, and 250 VDC at 0.27 amps. Connections are made via screw terminals on a 0.25-inch connector. Licensed electricians, HVAC technicians, and industrial controls specialists are the primary installers.

The 9012GRG5 is suited for use in residential and light commercial mechanical rooms, pump systems, compressor controls, and HVAC equipment where pressure-actuated switching is required. It is rated for vibration-resistant service, making it a reliable choice in environments with mechanical equipment. This switch is a replacement unit for use with the Square D 9012G series. It is packaged as a single unit and is appropriate for new installations or direct swap-out service work on existing 9012G series installations.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC or mechanical controls technician in accordance with NEC requirements and applicable local codes. De-energize the circuit and relieve system pressure before removing or installing this switch. Screw terminal connections should be made securely to prevent arcing under load. Verify that the supply voltage and current draw of the connected load do not exceed the rated values for the switch contact configuration in use.
