Indoor-Outdoor
NEMA 4X enclosure with 316 stainless steel construction provides corrosion resistance and environmental protection, reducing maintenance costs and downtime while enabling reliable outdoor installations. The rugged encapsulation protects windings and insulation from dust, moisture, and mechanical shocks, translating to longer service life and lower replacement cycles in harsh facilities. Copper windings deliver high electrical conductivity, improving efficiency and reducing heat losses, which supports lower energy costs and cooler operation in continuous duty applications. A 5 kVA rating paired with a 480 V primary and 120/240 V secondary supports standard facility power distributions and machine control panels, enabling quick integration into existing electrical infrastructures. Epoxy encapsulation and 60 Hz operation minimize vibration and thermal hot spots, contributing to stable output under load fluctuations and improving equipment protection. Two voltage taps at +2.5% FCAN and -2.5% FCBN provide practical voltage regulation to accommodate supply variations common in industrial environments. The indoor-outdoor Weathershield design simplifies installation across varied sites, while the 1774X frame and compact dimensions ease mounting in standard electrical rooms or outdoor cabinets. Overall, the transformer delivers robust resilience, predictable regulation, and long-term value for OEMs, panel builders, and maintenance teams.

FAQs
Plan for indoor or outdoor mounting using the 1774X frame and NEMA 4X enclosure. Ensure 480 V primary and 120/240 V secondary wiring is routed to compatible panels, with adequate clearance for cooling. Verify the 60 Hz single-phase configuration and use the +2.5%/ -2.5% taps to fine-tune voltage under load.
The unit provides 5 kVA with a 480 V primary and 120/240 V secondary, operating at 60 Hz in a single-phase arrangement. It uses copper windings and features two voltage taps (+2.5% FCAN, -2.5% FCBN) for regulation, with a 150 °C rise and NEMA 4X enclosure.
Yes. It is designed for indoor-outdoor use with a NEMA 4X enclosure and 316 stainless steel construction, providing corrosion resistance and environmental protection suitable for weather-exposed installations.
Copper windings offer high electrical conductivity, translating to lower I2R losses and better efficiency. This reduces operating heat, supports longer insulation life, and improves overall reliability in continuous-duty industrial applications.
Warranty is defined as one year from installation or 18 months from shipment, whichever comes first, under Eaton policy 25-000. Routine inspections, clean connections, and periodic insulation checks are recommended to maintain performance and extend service life.
