Built to NEMA Premium efficiency standards (IE3), this 405T frame motor delivers 95.4% nominal efficiency at 1780 RPM, ensuring optimal energy savings and reduced operational costs. Designed for continuous duty (S1) with a service factor of 1.15, it handles overload conditions up to 125% of rated load without derating. The Totally Enclosed Fan-Cooled (TEFC) enclosure provides IP56 protection against dust and water ingress, making it ideal for harsh environments including chemical plants, pulp and paper mills, and wastewater treatment facilities. Key electrical specifications include a rated current of 117 Amps, KVA code G, and insulation class F with tropicalization for enhanced durability in humid or corrosive conditions. The motor features a robust graphite grey coating (7024) and is UL/CSA/DoE certified, meeting stringent safety and performance standards. Bearings are pre-lubricated 6316 C3 (drive end) and 6314 C3 (non-drive end) for extended service life. With a rated ambient temperature of 40°C and altitude tolerance up to 1000 meters, this motor is optimized for global industrial use. Applications span pump systems, fans, compressors, and material handling equipment where consistent torque and high efficiency are critical. The SD3-405T-4-RR-E-100 is compatible with variable frequency drives (VFDs) for variable speed control, offering flexibility in modern automation systems. Certified for Class I Division 2 hazardous locations (Groups A, B, C, D), it ensures safe operation in explosive atmospheres. Backed by Techtop Industries' engineering expertise, this motor combines durability, efficiency, and compliance to deliver long-term value in demanding industrial environments.
