Overview

The TechTop CB3-AL-TF-56C-2-B-D-.33 is a high-efficiency, three-phase induction motor designed for industrial applications requiring reliable performance and energy savings. Rated at 0.33 HP (1/3 HP) with a 56C frame size, this motor delivers 1750 RPM at full load, making it ideal for constant-speed applications such as pumps, fans, and compressors. The motor operates on dual voltage (230V/460V, 60Hz) and is compatible with 50Hz systems, ensuring global versatility. With a TEFC (Totally Enclosed Fan-Cooled) enclosure, it provides superior protection against dust and moisture, rated IP55, and is certified for hazardous locations (Class 1, Div 2, Groups A-D). Key electrical specifications include a rated current of 1.34A at 230V and 0.67A at 460V, with a service factor of 1.25 for temporary overload capacity. The motor achieves a nominal efficiency of 74% (IE3 - NEMA Premium), reducing energy consumption and operational costs. It features a Class F insulation system with tropicalization for enhanced durability in harsh environments. The 9-lead dual-voltage wiring configuration simplifies installation and compatibility with variable frequency drives (VFDs) for speed control applications. Mechanical robustness is ensured with 6204ZZ sealed ball bearings on both drive-end (DE) and non-drive-end (NDE) sides, providing low maintenance and long service life. The motor weighs approximately 16 lbs and includes removable feet for flexible mounting options. Shaft grounding is standard to protect against bearing currents in inverter-driven systems. With a rated ambient temperature of 40°C and altitude tolerance up to 1000 meters, the CB3-AL-TF-56C-2-B-D-.33 is engineered for demanding industrial environments.
