Special features
Electrostatically Shielded
Feature → Business Impact → Application: The totally enclosed non-ventilated design protects windings from dust, moisture and debris, reducing maintenance cycles and downtime in factory floors and switchgear. This translates to higher equipment uptime and lower total cost of ownership for critical power distribution. Application-wise, it suits rugged industrial environments where reliability and enclosure integrity matter, such as manufacturing lines and processing plants. Feature → Business Impact → Application: Aluminum windings offer a lightweight, cost-effective balance with good conductivity, supporting efficient energy transfer and easier installation in large installations. The electrostatic shield minimizes EMI and stray capacitance, improving performance for nearby control systems and programmable logic controllers in control panels. Feature → Business Impact → Application: The K-4 design and PV/SV capabilities with 2 at +2.5% and 4 at -2.5% taps provide precise voltage regulation under varying load, reducing nuisance trips and extending motor life. Application includes motor drives and lighting circuits in variable-load scenarios. Feature → Business Impact → Application: Primary 480 V and secondary 208Y/120 V ratings align with common industrial utilities and equipment, simplifying panel integration and reducing bootleg transformer configurations. Application includes switchgear assemblies and distribution panels. Feature → Business Impact → Application: Frame 916AN, weight 881 lb, and dimensions 46.58 in H x 28.22 in W x 23.42 in D support straightforward mounting in standard enclosures, improving installation speed and compatibility with existing infrastructure. Feature → Business Impact → Application: The rugged enclosure and UL Listed certification provide regulatory peace of mind, while a 75 kVA rating covers a wide range of facility loads; warranty terms further reduce ownership risk and support long-term ROI.
