Overview

The TechTop CB1-AL-TF-145TC-4-B-C-2 is a 2 HP, 4-pole (1800 RPM) single-phase induction motor engineered for industrial reliability and energy efficiency. Built to NEMA Premium (IE3) standards, this motor delivers 1745 RPM at full load with a service factor of 1.15, ensuring consistent performance under variable loads. Rated for dual-voltage operation (115/208-230V, 60Hz), it features a totally enclosed fan-cooled (TEFC) enclosure with IP55 rating for protection against dust and water ingress, making it suitable for harsh environments. Key electrical specifications include a rated current of 17.6A (115V) / 8.78A (230V), locked rotor current of 52.66A, and a breakdown torque of 260% of full load. The motor incorporates a 500µF start capacitor and 80µF run capacitor for optimized starting and running performance. With NEMA Design L characteristics, it provides high starting torque while maintaining energy efficiency. The 145TC frame size ensures compatibility with standard mounting configurations, and the motor is tropicalized for enhanced durability in humid or corrosive conditions. Certified for industrial applications, the CB1-AL-TF-145TC-4-B-C-2 is ideal for pumps, fans, compressors, and material handling equipment. Its dual-voltage capability simplifies integration into existing systems, while the 6-lead wiring configuration allows for flexible voltage selection. The motor's graphite gray coating (7024) provides additional corrosion resistance, and the 6205-ZZ shielded ball bearings on both drive-end and non-drive-end sides ensure long service life with minimal maintenance. Weighing approximately 51.3 lbs, this motor combines energy efficiency, durability, and performance in a compact, NEMA Premium-rated package.
