Epoxy-encapsulated general-purpose transformer delivers superior winding protection and moisture resistance, while copper windings offer low resistance and high conductivity. The 15 kVA rating with 480 V primary and 120/240 V secondary configuration provides reliable, code-compliant power for control panels and feeders, improving voltage stability and machine uptime. The single-phase design at 60 Hz supports common facility electrical architectures, simplifying integration with existing switchgear and panelboards. Grade 304 stainless steel enclosure with NEMA 3R rating and Weathershield construction protects windings from moisture, dust, and cleaning processes, reducing maintenance costs and enabling safe servicing in both indoor and outdoor environments such as warehouses, loading docks, and outdoor equipment pads. Compact footprint and sturdy frame facilitate installation in tight spaces; dimensions of 10.52 in depth, 13.38 in width, and 19 in height, along with a 250 lb weight, support secure mounting on standard bases and enclosures. UL Listed certification ensures compliance with safety standards for industrial transformers, while 60 Hz single-phase operation aligns with typical facility power systems and a 115°C rise rating keeps insulation within limits under heavy loads. Warranty coverage follows Eaton's policy of one year from installation or eighteen months from shipment, providing practical assurance during commissioning and ongoing operation.
