Rated at 460 volts (also configurable at 230 volts) across a 60 Hz supply, it delivers a full-load speed of 1775 RPM on a 326T steel frame with OPSB (open protected splash-proof) enclosure. Insulation Class H and a 1.15 service factor allow the motor to handle intermittent overloads without thermal degradation. The inverter-ready design makes it compatible with variable frequency drive installations where speed control or soft-start capability is required.\u003c\/p\u003e\u003cp\u003eThis motor is suited for general-purpose industrial applications including pumps, compressors, fans, and conveyor drives in commercial and light-industrial facilities. The OPSB enclosure is appropriate for indoor or sheltered outdoor locations where splash exposure is possible but full submersion or heavy particulate ingestion is not. The F1 mounting arrangement and rigid base allow direct mounting to a bedplate or structural skid. Installation is typically performed by licensed industrial electricians or mechanical contractors familiar with large-frame motor alignment and NEC requirements for motor branch circuits.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e50 HP output at 60 Hz with a 1775 RPM full-load speed and 1800 RPM synchronous speed\u003c\/li\u003e\n\u003cli\u003eNEMA Premium efficiency rating — 94.5 percent efficiency at 100 percent load\u003c\/li\u003e\n\u003cli\u003eInverter-ready design supports variable frequency drive operation\u003c\/li\u003e\n\u003cli\u003eClass H insulation with a 1.15 service factor for continuous-duty overload tolerance\u003c\/li\u003e\n\u003cli\u003ePolyrex EM bearing grease rated from -20 degrees F to 300 degrees F for wide ambient range\u003c\/li\u003e\n\u003cli\u003eReversible shaft rotation with standard lifting lugs and shaft grounding included\u003c\/li\u003e\n\u003cli\u003e9-lead configuration at 8 AWG flying leads enables dual-voltage wiring (460 V or 230 V)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style general-purpose replacement or new-installation motor for three-phase, 326T frame applications requiring a 50 HP NEMA Premium motor with OPSB enclosure and F1 mounting.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with NEC Article 430 governing motor branch circuits, overload protection, and disconnecting means. Disconnect and lock out all power sources before handling motor leads or making mechanical connections. Verify shaft alignment with the driven load using a dial indicator before final coupling torque, and confirm that the VFD carrier frequency and output filter settings are compatible with the motor nameplate ratings when used in inverter applications. Do not energize the motor without confirming that overload protection is sized to the actual full-load amp draw at the selected voltage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput\u003c\/strong\u003e: 50 HP at 60 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull-Load Speed\u003c\/strong\u003e: 1775 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSynchronous Speed\u003c\/strong\u003e: 1800 RPM at 60 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase\u003c\/strong\u003e: Three Phase\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency\u003c\/strong\u003e: 60 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 460 volts \/ 230 volts at 60 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull-Load Amps\u003c\/strong\u003e: 57 amps at 460 volts \/ 114 amps at 230 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEfficiency at 100% Load\u003c\/strong\u003e: 94.5 percent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Factor\u003c\/strong\u003e: 87\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eService Factor\u003c\/strong\u003e: 1.15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Class\u003c\/strong\u003e: H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnclosure\u003c\/strong\u003e: OPSB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame\u003c\/strong\u003e: 326T\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Poles\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Arrangement\u003c\/strong\u003e: F1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase\u003c\/strong\u003e: Rigid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 27.69 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Diameter\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Lead Quantity and Wire Size\u003c\/strong\u003e: 9 leads at 8 AWG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Lead Termination\u003c\/strong\u003e: Flying Leads\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearing Grease Type\u003c\/strong\u003e: Polyrex EM (-20 degrees F to 300 degrees F)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePulley End Bearing Type\u003c\/strong\u003e: Ball\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Rotation\u003c\/strong\u003e: Reversible\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Grounding\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInverter Ready\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStarting Method\u003c\/strong\u003e: Direct on line\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuty Rating\u003c\/strong\u003e: Continuous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmbient Temperature\u003c\/strong\u003e: 40 degrees C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeed\u003c\/strong\u003e: Single Speed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Standards\u003c\/strong\u003e: NEMA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEfficiency Certification\u003c\/strong\u003e: NEMA Premium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAgency Approvals\u003c\/strong\u003e: CURUSEEV\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Family\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Type\u003c\/strong\u003e: 4256M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKVA Code\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesign Code\u003c\/strong\u003e: A\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CARRIER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: em2543t-g\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARRIER","offers":[{"title":"Default Title","offer_id":51138540699954,"sku":"EM2543T-G","price":5851.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305532399.jpg?v=1778258878","url":"https:\/\/voomisupply.com\/products\/carrier-em2543t-g-50-hp-326t-three-phase-opsb-motor","provider":"Voomi Supply","version":"1.0","type":"link"}
