Overview

The Techtop GR3-CI-OP-444T-4-RR-E-150 is a high-efficiency, three-phase, 150 HP industrial motor designed for continuous duty applications in demanding industrial environments. Built to NEMA Premium efficiency standards (IE3), this motor delivers 95.8% nominal efficiency at 460V, 60Hz, reducing energy consumption and operational costs while meeting DOE and CSA compliance requirements. The 444T frame size ensures compatibility with standard mounting configurations, while the TEFC (Totally Enclosed Fan-Cooled) enclosure provides robust protection against dust, moisture, and harsh conditions, rated IP55. Key electrical specifications include a rated current of 330/165 Amps (high/low voltage), a service factor of 1.15, and a nominal power factor of 0.89. The motor operates at 1785 RPM with a locked rotor torque of 232% of full load, ensuring reliable startup under heavy loads. With a temperature rise of 34.9°C at full load and tropicalization treatment, this motor is engineered for reliability in elevated ambient temperatures up to 40°C. The 12-lead dual-voltage wiring configuration allows flexible installation for either 230V or 460V operation, simplifying integration into existing systems. Mechanical robustness is ensured with C3-class bearings on both the drive-end (DE) and non-drive-end (NDE) sides, supporting long service life under continuous operation. The motor’s graphite grey coating (7024) provides additional corrosion resistance, while the removable feet design facilitates easy installation and maintenance. Certified by UL, CSA, and DOE, this motor meets stringent safety and efficiency standards for industrial applications. Ideal for pumps, fans, compressors, and material handling systems, the GR3-CI-OP-444T-4-RR-E-150 is optimized for high-torque, continuous-duty applications where energy efficiency and durability are critical. Its compact 444T frame size and 1348.6 lb weight balance performance with space efficiency, making it a versatile choice for OEMs and end-users alike.
