Resin-encapsulated construction with copper windings provides superior moisture resistance and robust thermal performance, reducing insulation degradation in humid or dirty environments and extending service life, which translates to fewer unplanned outages and lower maintenance costs in hazardous-area facilities. The 60 Hz three-phase design delivers improved efficiency and voltage regulation for mid-to-heavy loads, supporting reliable motor and drive performance in production lines and processing plants. With a 480 Vac primary to 240 Vac secondary configuration, integration with existing switchgear and MCCs is streamlined, lowering installation time and wiring errors while enabling smoother panel upgrades. The painted steel housing and NEMA 4 enclosure offer durable protection against dust, water ingress, and corrosion, reducing cumulative maintenance and enabling outdoor or harsh-environment deployments. NEC/CEC compliance plus Class I Division 2 hazardous-area rating mitigate regulatory risk and support safe operation in process plants, chemical facilities, and oil & gas applications. Documentation and compatibility with XDT/XTT design packages ensure engineers can source, design, and install with confidence, minimizing project risk and accelerating commissioning.
