Overview

The Techtop GR3-CI-TF-324TC-6-BR-D-25 is a 25 HP, three-phase, cast iron motor engineered for industrial reliability. Built to NEMA Premium IE3 standards, this motor delivers 93% nominal efficiency at 60Hz and 50Hz, reducing energy consumption and operating costs. The 324TC frame size ensures compatibility with standard mounting configurations, while the TEFC (Totally Enclosed Fan Cooled) enclosure protects internal components from dust, moisture, and harsh environments. Key electrical specifications include dual voltage operation at 230/460V, 60Hz and 230/460V, 50Hz, with rated currents of 62.2A (230V) and 31.1A (460V). The 6-pole design (1180 RPM synchronous speed) provides robust torque output, with a service factor of 1.25 for temporary overload conditions. Rated ambient temperature is 40°C, and the motor is tropicalized for enhanced durability in humid or corrosive environments. Mechanical robustness is ensured with 6312 C3 bearings on both drive-end (DE) and non-drive-end (NDE) sides, supporting reliable operation under heavy loads. The motor’s insulation class F and temperature rise of 57.8°C at full load contribute to long service life. Certified to UL, CSA, and DOE standards, this motor meets stringent safety and efficiency requirements for industrial use.
