Voltage Rating
460 V
Feature → Business Impact → Application: TEFC enclosure protects critical windings from dust and moisture in rugged environments, increasing motor life and reliability for crushers and conveyors. This translates to higher uptime and lower maintenance costs in mining and aggregate plants, where dust and vibration are persistent. Feature → 350 HP, 460 V, 3-phase input supports high-torque starts and consistent performance across continuous duty cycles, reducing voltage sag issues and improving line efficiency in heavy material handling systems. Feature → Premium Efficiency with Insulation Class F lowers energy consumption by delivering better power factor and reduced energy costs over the motor’s life, beneficial for long-running conveyors and grinding operations. Feature → Frame Size 449T with Foot Mount and NEMA Design Code A enables straightforward installation, compatibility with standard motor bases, and quicker retrofit or expansion in existing lineups. Feature → Direct On Line starting and 0 day lead time stock simplifies project timelines and minimizes commissioning risk, especially in regional builds and remote sites. Feature → Bearing arrangement 6318 | Ball combined with robust shaft design (3.38 in) supports high radial loads and long service intervals, reducing shaft-related downtime and maintenance efforts at crushers and mills. These characteristics collectively enable measurable gains in reliability, energy efficiency, and operating cost reduction for industrial installations requiring sturdy, compliant, and easy-to-install motors.
