Overview

The Techtop GR3-CI-TF-143T-4-B-F-1 is a 1 HP, three-phase, cast iron TEFC motor designed for industrial applications requiring reliable, high-efficiency operation. Built to NEMA Premium IE3 efficiency standards, this motor delivers 85.5% nominal efficiency at a rated speed of 1740 RPM, ensuring energy savings and reduced operational costs. With a 575V, 60Hz power supply, it is optimized for high-voltage industrial environments, including Class 1, Division 2 hazardous locations (Groups A, B, C, D). Key mechanical features include a 143T frame size, dual 6205ZZ shielded ball bearings for durability, and a graphite grey 7024 coating for corrosion resistance. The motor’s tropicalized design ensures reliable performance in humid or corrosive conditions, while its IP55 rating provides protection against dust and water ingress. The 9-lead dual-voltage wiring configuration allows flexible installation across different voltage systems, and the removable feet simplify mounting in tight spaces. Ideal for pumps, fans, compressors, and material handling equipment, the GR3-CI-TF-143T-4-B-F-1 combines robust construction with compliance to UL, CSA, and DOE standards. Its service factor of 1.25 provides additional headroom for temporary overloads, and the 1.2A rated current at full load ensures efficient power consumption. With a temperature rise of just 36°C at full load, this motor operates cooler and extends bearing and winding life. Backed by Techtop Industries’ reputation for quality, this motor is a cost-effective solution for demanding industrial applications.
