Rated at 575 VAC with a Line-Load-Load-Line terminal configuration, this switch monitors fluid levels and triggers control circuits when the float reaches a set point. It ships with the float, float switch assembly, and rod included. Licensed electricians and instrumentation technicians typically specify this switch for pump control, sump monitoring, and process tank level management where a NEMA 4 enclosure rating is required for protection against water ingress and splashing.\u003c\/p\u003e\u003cp\u003eThe 9037HW33 is suited for industrial pump control panels, wastewater lift stations, commercial sump systems, and process fluid tanks that require reliable level detection. The NEMA 4 rating makes it appropriate for indoor and outdoor installations where the switch may be exposed to splashing water or hose-directed water. The DPST contact form allows the switch to simultaneously open or close two separate circuits, supporting both control and indication functions within a single device.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDPST contact form simultaneously controls two circuit paths\u003c\/li\u003e\n\u003cli\u003e575 VAC rating supports higher-voltage industrial control applications\u003c\/li\u003e\n\u003cli\u003eNEMA 4 enclosure rating provides protection from water splash and ingress\u003c\/li\u003e\n\u003cli\u003eLine-Load-Load-Line terminal layout simplifies wiring to panel circuits\u003c\/li\u003e\n\u003cli\u003eIncludes float, float switch, and rod for complete out-of-box installation\u003c\/li\u003e\n\u003cli\u003eMeets CE, CSA, RoHS, UL 508, and UL Listed File E12158 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement float switch for industrial and commercial level control applications requiring a DPST, NEMA 4 rated device at 575 VAC with a Line-Load-Load-Line terminal configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with NEC requirements for the application environment. De-energize the circuit and verify absence of voltage before making any wiring connections. Ensure the float rod length and mounting orientation are appropriate for the tank or sump depth before securing the switch. Verify terminal torque and conduit sealing requirements per local code and the manufacturer installation sheet.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 575 VAC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Form\u003c\/strong\u003e: DPST\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNEMA Rating\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Type\u003c\/strong\u003e: Line-Load-Load-Line\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Float, Float Switch, Rod\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 15 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 10.11 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards Met\u003c\/strong\u003e: CE, CSA File LR25490, RoHS Compliant, UL 508, UL Listed File E12158\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 39122210\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SQUARE D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9037HW33\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51539577110834,"sku":"9037HW33","price":660.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/955a01f8cc108b859e7f10bc2bc07b54.jpg?v=1785843372","url":"https:\/\/voomisupply.com\/products\/square-d-9037hw33-float-switch-dpst-nema-4-575-vac","provider":"Voomi Supply","version":"1.0","type":"link"}
