Overview

The Techtop GR3-CI-TF-160MB35-2-BR-D-20 is a 20 HP, three-phase, metric IEC motor engineered for heavy-duty industrial applications requiring reliable, high-efficiency performance. Built with a 160MB35 frame size, this motor operates at 3550 RPM (2 pole) and delivers consistent power output under demanding conditions. Its Totally Enclosed Fan Cooled (TEFC) design ensures protection against dust, moisture, and harsh environments, achieving an IP55 rating for ingress protection and NEMA Design A classification for robust performance. Key electrical specifications include dual voltage compatibility (230/460V at 60Hz and 230/460V at 50Hz), with rated currents of 45.5A (low voltage) and 22.7A (high voltage). The motor achieves a nominal efficiency of 91% and a power factor of 0.91 cosθ, meeting IE3 - NEMA Premium efficiency standards. It features a service factor of 1.15, allowing for temporary overloads up to 125% of rated load without performance degradation. The insulation class is F, with a temperature rise of 52.2°C at full load and a maximum ambient operating temperature of 40°C. Mechanical robustness is ensured with C3-grade bearings (6309 C3 on both drive-end and non-drive-end sides) and a cast iron construction for durability. The motor includes a removable conduit box with M32 x 1.5 cable entry for simplified wiring and installation. It is coated in 7024 Graphite Grey for enhanced corrosion resistance and is rated for Class 1, Division 2, Groups A, B, C, and D hazardous locations. The motor weighs approximately 281.6 lbs and is designed for continuous duty operation at altitudes up to 1000 meters.
