Indoor-Outdoor
Encapsulated EP construction with aluminum windings provides robust durability and efficient heat dissipation. This design reduces corrosion risk and extends service life in harsh environments, cutting maintenance costs and downtime. It's well-suited for control panels and automation enclosures in spaces where compact footprint and reliability matter. The NEMA 3R enclosure offers weather protection for indoor-outdoor service, enabling outdoor installation and safer operation in variable climates. This makes it ideal for outdoor control stations, remote substations, and equipment rooms that require dependable protection against rain, dust, and temperature fluctuations. With a 7.5 kVA, single-phase configuration (400 V primary, 120/240 V secondary) rated for 50/60 Hz, it supports a wide range of automation loads and lighting circuits with stable voltage, improving equipment performance and energy efficiency. Voltage taps at +2.5% FCAN and -2.5% FCBN provide precise regulation, protecting sensitive electronics and maintaining performance under supply fluctuations. The unit’s 196 lb weight and 10.52 in x 13.38 in x 19 in footprint facilitate flexible mounting and straightforward installation in new builds or retrofit projects, all backed by Eaton’s warranty and service support.
