Overview

The Techtop SD3-286TC-4-BR-E-30 is a 30 HP, 4-pole (1800 RPM) severe duty industrial motor engineered for continuous operation in demanding environments. Rated at 460V, 60Hz, 3-phase, this NEMA Premium IE3 motor delivers 93.6% nominal efficiency, ensuring energy savings and compliance with DOE regulations. With a service factor of 1.25, it handles temporary overloads up to 25% above rated load without derating. The TEFC (Totally Enclosed Fan-Cooled) enclosure provides IP56 protection against dust and water ingress, making it ideal for harsh industrial settings, including hazardous locations (Class 1 Div 2 Groups A-D). Key mechanical features include a 286TC frame size, 6311 C3 bearings on both drive-end (DE) and non-drive-end (NDE) sides, and a removable 1.25" cable entry for simplified wiring. The motor operates at a rated ambient temperature of 40°C and an altitude up to 1000 meters, with a temperature rise of 62°C at full load. Tropicalization ensures reliability in humid or corrosive conditions. Certified by UL, CSA, and DOE (File Nos. 323353, 224693, 096A), this motor meets stringent safety and performance standards. Applications include pumps, fans, compressors, conveyors, and other heavy-duty industrial machinery requiring high torque and sustained performance. The motor's graphite grey 7024 coating provides corrosion resistance, while shaft grounding prevents bearing damage from electrical discharge. With a full-load torque of 119.17 ft-lb and a breakdown torque of 226% of rated load, it delivers robust performance under variable loads. Choose the Techtop SD3-286TC-4-BR-E-30 for reliable, high-efficiency operation in severe-duty industrial environments.
