The coil operates at 208 to 240 volts AC at 60 Hz and 220 volts AC at 50 Hz, making it compatible with standard single-phase and three-phase power distribution found across North American and select international installations. It ships in a NEMA 1 enclosed configuration, which protects internal contacts from dust and incidental contact in indoor environments. Licensed electricians and HVAC-R technicians are the primary installers of this type of contactor.\u003c\/p\u003e\n\u003cp\u003eThis contactor is suited for both residential and light commercial applications where a definite purpose switching device is required. Typical installation scenarios include rooftop units, condensing units, chiller panels, and compressor circuits. Horsepower ratings span a wide range: 3 HP at 115 volts AC, 10 HP single-phase and 15 HP three-phase at 230 volts AC, 30 HP at 460 volts AC, and 30 HP at 575 volts AC. This flexibility makes the 8911DPSG53V09 a practical replacement or upgrade contactor across multiple system voltage classes without requiring a different part number for each voltage tier.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-pole configuration handles single-phase and three-phase motor loads up to 50 amps inductive\u003c\/li\u003e\n  \u003cli\u003eCoil rated for 208 to 240 volts AC at 60 Hz and 220 volts AC at 50 Hz\u003c\/li\u003e\n  \u003cli\u003eNEMA 1 enclosed design provides indoor protection against dust and accidental contact\u003c\/li\u003e\n  \u003cli\u003eWide horsepower range: 3 HP at 115V AC through 30 HP at 460V and 575V AC\u003c\/li\u003e\n  \u003cli\u003eMeets NEMA 1 standards for enclosed industrial and commercial control equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style definite purpose contactor replacement for 3-pole, 50-amp inductive load applications operating on 208 to 240 volt AC coil circuits in HVAC, refrigeration, and motor control panels.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician or qualified HVAC-R technician in accordance with the National Electrical Code (NEC) and any applicable local codes. Always disconnect and lock out power to the panel or unit before removing or installing a contactor. Verify coil voltage and pole configuration match the existing circuit before energizing. Do not exceed the published inductive load amperage rating for the application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Poles\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInductive Load Rating\u003c\/strong\u003e: 50 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoil Voltage\u003c\/strong\u003e: 208 to 240 volts AC at 60 Hz, 220 volts AC at 50 Hz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower Rating (115V AC, 1-phase)\u003c\/strong\u003e: 3 HP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower Rating (230V AC, 1-phase)\u003c\/strong\u003e: 10 HP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower Rating (230V AC, 3-phase)\u003c\/strong\u003e: 15 HP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower Rating (460V AC)\u003c\/strong\u003e: 30 HP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower Rating (575V AC)\u003c\/strong\u003e: 30 HP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnclosure Type\u003c\/strong\u003e: Enclosed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards Met\u003c\/strong\u003e: NEMA 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 8911DPSG53V09\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51541544337714,"sku":"8911DPSG53V09","price":834.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e7f1aeed49a675b4e5e97350745aa8c_da563560-6d38-4707-ba6c-bf9fa7c843ae.jpg?v=1785878948","url":"https:\/\/voomisupply.com\/products\/square-d-8911dpsg53v09-definite-purpose-contactor-3p-50a","provider":"Voomi Supply","version":"1.0","type":"link"}
