The Square-D Pressure Switch Type-G is designed for reliable performance in various well applications to provide dependable pressure control and long-term value. When pressure drops to the cut-in point, the switch starts the pump, and when pressure rises to the cut-out point, it shuts the pump off. This heavy-duty switch operates within a pressure range of 30 to 50 PSI, making it ideal for maintaining steady household water pressure by cycling well pumps on and off. Its robust mechanical design supports reliable performance and a long service life.
Durable construction for long-lasting use
Adjustable operating range from 30 to 50 PSI, suitable for home and industrial use
Compatible with a wide range of pumps and tanks
Easy installation and maintenance, with installation-ready design and routine inspection of diaphragm wear and terminal corrosion for long-term performance
The Square-D Telemecanique Type-G pressure switch is a heavy-duty Square D pressure switch with an adjustable 30 to 50 PSI range, built to control electrically driven water pumps by starting the pump at the cut-in pressure and stopping it at the cut-out pressure for consistent pressure management. For homeowners, contractors, and commercial users running well water systems, residential or commercial pumping systems, or industrial equipment, it is a common choice when reliable, adjustable pressure control matters.
The switch uses a diaphragm for pressure response, while the spring mechanism sets the cut-in and cut-out thresholds. It features a DPST contact arrangement, adjustable differential, a 0.25 inch NPSF pressure connection, and a general purpose indoor NEMA 1 enclosure, with a pressure adjustment mechanism that lets users calibrate cut-in and cut-out pressures to system requirements.
This pressure switch is installed as part of a pump or compressor control system and should be set up carefully according to the product specifications.
Disconnect power to the system before beginning installation or service.
Mount the switch using its bracket in an indoor general purpose location.
Connect the pressure port using the 0.25 inch NPSF connection.
Make the electrical connections at the screw clamp terminals according to the system requirements.
Confirm the pressure setting and adjustable differential match the application before returning the system to operation.
