Overview

The TechTop GR3-CI-TF-160MB3-2-BR-D-15 is a 15 HP, three-phase IEC metric motor engineered for industrial applications requiring high efficiency and reliable performance. Built to NEMA Premium (IE3) efficiency standards, this motor delivers 91% nominal efficiency at 3550 RPM, reducing energy consumption and operational costs. Rated for dual-voltage operation (230/460V, 60Hz; 230/460V, 50Hz), it supports flexible installation in global markets. The motor features a Totally Enclosed Fan-Cooled (TEFC) enclosure with IP55 rating, providing robust protection against dust and water ingress in harsh environments. Its NEMA Design A compatibility ensures seamless integration with variable frequency drives (VFDs) for energy-efficient speed control. Key electrical specifications include a service factor of 1.15, locked rotor torque of 297%, and breakdown torque of 317%, ensuring reliable startup under load. The motor operates at a rated ambient temperature of 40°C and has a temperature rise of 56.8°C at full load. Mechanical features include 6309 C3 bearings on both drive-end (DE) and non-drive-end (NDE) sides, a graphite grey 7024 corrosion-resistant coating, and a removable foot design for ease of installation. The 160MB3 frame size is standard for IEC metric applications, with a cable entry size of M32 x 1.5. Weighing 273 lbs, it is optimized for continuous duty (S1) operation. Certified for Class 1, Division 2, Groups A-D hazardous locations, this motor is ideal for pumps, fans, compressors, and material handling systems where high torque and sustained performance are critical. Its tropicalization treatment enhances resistance to humidity and environmental stress, extending service life in tropical or coastal settings.
