Square D 9036GR1 Float Switch Dpst Nema 7 9 575 Vac

Product Description

The SQUARE D 9036GR1 is a double-pole single-throw (DPST) float switch designed for pressure and level sensing applications in industrial and commercial environments. Rated for 575 VAC with a Line-Load-Load-Line terminal configuration, this switch is built to operate reliably in hazardous and demanding locations. It carries NEMA 7 and NEMA 9 enclosure ratings, making it suitable for use in environments where explosion-proof or dust-ignition-proof protection is required. Licensed electricians and industrial maintenance technicians install this switch as part of pump control, tank level monitoring, and fluid management systems.

The 9036GR1 is applied in residential, commercial, and industrial settings where float-actuated switching controls pumps, alarms, or other electrical loads based on fluid level. Its NEMA 7 and NEMA 9 ratings qualify it for use in classified hazardous locations, including areas with flammable gases or combustible dust. The Line-Load-Load-Line terminal layout supports straightforward wiring into existing control circuits. This switch is commonly used in sump, wastewater, chemical, and process fluid applications where reliable level detection is critical.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes for classified hazardous locations. Disconnect and lockout all power to the circuit before handling or wiring the switch. Verify the enclosure rating matches the hazardous location classification at the installation site before mounting. Do not exceed the rated voltage or current capacity of the switch contacts.
