Overview

The TechTop SS3-TF-143TC-4-D-1-RND is a 1 HP, 3-phase, 60Hz (50Hz compatible) Totally Enclosed Fan-Cooled (TEFC) stainless steel motor designed for industrial applications requiring high efficiency and durability. This NEMA Premium IE3 motor meets DOE compliance with a nominal efficiency of 85.5% and a service factor of 1.25, ensuring reliable operation under variable loads. The 143TC frame size provides a compact footprint while accommodating a 230/460V dual-voltage input, making it suitable for both North American and international installations. Key electrical specifications include a rated current of 3.08/1.54 Amps (230V/460V), full-load torque of 2.97 Ft-Lb, and a breakdown torque of 399%. The motor operates at 1750 RPM with a slip of 2.78% at full load and features a Class F insulation system with tropicalization for enhanced environmental resistance. Certified to UL, CSA, and DOE standards (File Nos. 323353, 224693, 096A), this motor is ideal for hazardous and non-hazardous locations where corrosion resistance and mechanical robustness are critical. Mechanical features include sealed bearings (6205 2RS DE side, 6204 2RS NDE side), a shaft grounding system (optional), and a NEMA Design B torque curve optimized for general-purpose industrial applications. The motor’s IP69K rating ensures protection against high-pressure water jets and dust ingress, while its unpainted stainless steel construction provides superior corrosion resistance in wet or chemically aggressive environments. Applications include pumps, fans, compressors, conveyors, and machine tools in food processing, pharmaceuticals, chemical processing, and wastewater treatment facilities. The 9-lead dual-voltage wiring configuration allows flexible installation in both 230V and 460V systems without modification, reducing downtime and inventory complexity. With a rated ambient temperature of 40°C and an altitude rating of 1000 meters, this motor is engineered for consistent performance in demanding industrial settings.
