Square D 9036DW31R Float Switch Dpst Nema 4 575 Vac

Product Description

The SQUARE D 9036DW31R is a double-pole single-throw (DPST) float switch designed for level and pressure control applications in industrial and commercial environments. Rated for 575 VAC operation, this switch features a Line-Load-Load-Line terminal configuration that simplifies field wiring. The NEMA 4 enclosure rating provides protection against windblown dust and rain, splashing water, and hose-directed water, making it suitable for demanding indoor and outdoor service conditions. Licensed electricians and controls technicians typically install and service this type of switch as part of pump control panels, sump systems, or process level monitoring circuits.

The 9036DW31R is suited for residential, commercial, and light industrial float switch applications where liquid level monitoring or pressure-driven switching is required. Typical installations include pump control panels, HVAC condensate systems, sump pump controls, and process tanks where reliable DPST switching action is needed. The 575 VAC rating accommodates higher-voltage three-phase service environments common in Canadian and industrial North American installations. No specific compatible model numbers are listed in the available product data.

Key Features

• DPST contact form provides simultaneous switching of two circuits with a single actuator
• 575 VAC rating supports higher-voltage industrial and Canadian service applications
• NEMA 4 enclosure protects against dust, rain, and hose-directed water
• Line-Load-Load-Line terminal layout simplifies panel wiring and reduces installation time
• Meets CE, CSA, UL 508, and RoHS requirements for broad compliance across jurisdictions

Compatibility

Designed as an OEM-style replacement float switch for industrial pump control panels and level monitoring circuits requiring a DPST configuration at 575 VAC with a NEMA 4 enclosure rating.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the NEC and any applicable local codes. De-energize the panel and lock out and tag out the circuit before removing the existing switch or making wiring connections. Verify the supply voltage matches the 575 VAC rating of this switch before energizing. Do not exceed the switch contact ratings, and ensure the enclosure cover is fully secured before restoring power.
