Overview

The Techtop GR3-CI-TF-145T-2-B-D-2 is a 2 HP, three-phase, cast iron TEFC (Totally Enclosed Fan Cooled) motor engineered for industrial applications requiring reliable, high-efficiency operation. Designed with a 145T frame size, this motor delivers 3500 RPM at full load with a service factor of 1.25, ensuring robust performance under varying load conditions. The dual-voltage configuration (230/460V, 60Hz or 230/460V, 50Hz) provides flexibility for global installations, while the NEMA Premium efficiency rating (85%) reduces energy consumption and operational costs. Key electrical specifications include a rated current of 5.2/2.6 Amps (high/low voltage), a locked rotor current of 23.6 Amps, and a breakdown torque of 362%. The motor features a KVA code of H, insulation class F, and a temperature rise of 47.4°C at full load, meeting stringent thermal performance standards. Certified to UL, CSA, and DOE standards, the GR3-CI-TF-145T-2-B-D-2 is suitable for hazardous locations (Class 1, Div 2, Groups A-D) and operates efficiently at altitudes up to 1000 meters. Mechanically, the motor is built with 6205ZZ bearings on both the drive end (DE) and non-drive end (NDE) sides, providing durability and low maintenance. The graphite grey coating (7024) offers corrosion resistance, while the tropicalized design ensures reliable performance in humid or chemically aggressive environments. The motor’s IP55 rating and removable feet enhance installation versatility, and the 9-lead dual-voltage wiring configuration simplifies integration into existing systems. Ideal for pumps, fans, compressors, and material handling equipment, the GR3-CI-TF-145T-2-B-D-2 delivers consistent torque (3.02416 Ft-Lb at full load) and low noise levels (per NEMA standards). Its compact 145T frame size and 48.4 kg weight make it a space-efficient choice for OEMs and end-users seeking a high-reliability, energy-efficient motor solution.
