Overview

The TechTop GR3-CI-TF-365JM-4-BR-D-75 is a 75 HP, three-phase, totally enclosed fan-cooled (TEFC) cast iron motor designed for industrial applications requiring high efficiency and reliability. Built to NEMA Premium IE3 standards, this motor delivers 95.4% nominal efficiency at 1780 RPM, ensuring lower energy costs and compliance with DOE regulations. The 365JM frame size provides robust construction with a service factor of 1.15, allowing temporary overload operation without derating. Key electrical specifications include dual-voltage operation (230/460V, 60Hz; 230/460V, 50Hz) with rated currents of 167.2A (high voltage) and 83.6A (low voltage). The motor features NEMA Design A performance with a breakdown torque of 297% of full load and a locked rotor torque of 328%. With a Class F insulation system and tropicalization for harsh environments, it operates reliably in ambient temperatures up to 40°C and altitudes up to 1000 meters. Mechanical durability is ensured through C3-class bearings (6313 DE/NDE) and a graphite grey 7024 coating for corrosion resistance. The motor includes a removable lifting eye, 1.25" cable entry, and meets UL/CSA/CEC certifications. Ideal for pumps, fans, compressors, and material handling systems, this motor is optimized for variable frequency drive (VFD) operation with a Class 1, Division 2 hazardous location rating for use in explosive atmospheres.
