Overview

The Techtop SD3-449TSC-2-BR-E-250 is a severe-duty IEEE 841 compliant 250 HP motor designed for high-efficiency industrial applications. This 449TSC frame motor operates at 460V, 60Hz, delivering 3570 RPM with a 2-pole configuration. Rated at NEMA Premium IE3 efficiency (95.8%), it meets DOE and CSA standards for energy savings and reliability. The totally enclosed fan-cooled (TEFC) enclosure provides IP56 protection against dust and water ingress, making it suitable for harsh environments. With a service factor of 1.15 and tropicalization for extreme conditions, this motor handles overloads up to 125% of rated load without derating. Key features include a 269A rated current, 496 ft-lb full-load torque, and Class F insulation with an 83.4°C temperature rise. Certified by UL, CSA, and DOE, the SD3-449TSC-2-BR-E-250 is ideal for pumps, compressors, and heavy machinery in industrial facilities. Its graphite grey 7024 coating resists corrosion, while shaft grounding prevents bearing damage from electrical discharge. The motor's 2321.7 lb weight and 1000m rated altitude ensure compatibility with most industrial setups. Backed by Techtop's robust design and 6316 C3 bearings, this motor delivers consistent performance in continuous duty applications.
