Overview

The Techtop GR3-CI-TF-326T-6-BR-F-30 is a 30 HP, three-phase, cast iron motor designed for heavy-duty industrial applications. Built with a 326T frame size, this motor delivers 1180 RPM at full load with a 6-pole configuration, optimized for 575V, 60Hz operation. The service factor of 1.25 allows for temporary overloads up to 25% above rated power, while the full load torque of 132.4 Ft-Lb ensures reliable performance under demanding conditions. The insulation class F rating supports operation in ambient temperatures up to 40°C and altitudes up to 1000 meters. Key mechanical features include 6312 C3 bearings on both the drive end (DE) and non-drive end (NDE) sides, a 1.25" cable entry, and removable feet for flexible mounting options. The motor is equipped with a 12-lead dual voltage wiring configuration (230|460V), allowing for versatile installation. The graphite grey (7024) coating enhances durability and corrosion resistance. Applications include pumps, fans, compressors, conveyors, and other industrial machinery requiring reliable, high-efficiency motor performance. The motor is designed for continuous duty cycles and is optimized for use with variable frequency drives (VFDs) within the specified CT VFD range. With a weight of approximately 680 lbs and a locked rotor current of 297% of full load, this motor is built to handle the rigors of industrial operations while maintaining efficiency and longevity.
