Encapsulated hazardous-location design reduces ignition risk and simplifies regulatory compliance in Class I Division 2 zones, enabling safer startup and ongoing operation in oil & gas, chemical processing, and mining environments. This translates to lower risk of costly downtime and easier plant approvals, especially for distributed power on hazardous-site equipment. The 15 kVA three-phase unit with a 480 V primary and 208Y/120 V secondary delivers reliable voltage transformation for common facility distributions, supporting consistent downstream performance on critical equipment and control panels. Two taps at -5% FCBN provide voltage headroom to compensate line drops and maintain performance without costly upstream changes. A rugged NEMA 3R enclosure and the Weathershield indoor-outdoor design offer installation flexibility, whether used indoors, outdoors, or in weather-exposed locations, reducing site-specific engineering. Aluminum windings contribute durability and corrosion resistance, supporting long service life with minimal maintenance in harsh environments. UL Listed certification and Class 1 Division 2 compliance further assure reliability and regulatory acceptance, helping justify project ROI and maintenance planning with confidence.

FAQs
Installers should verify the Class I Division 2 rating for the site, mount the unit on a stable, non-combustible surface, and provide adequate enclosure clearance per NEMA 3R guidelines. Wiring should use the 70A connection, with attention to proper heat dissipation and short-circuit protection. The 480V to 208Y/120V outputs require correct circuit protection and voltage regulation during commissioning.
The transformer is a three-phase device rated at 15 kVA with a 480 V primary and a 208Y/120 V secondary. It operates at 50/60 Hz and uses aluminum windings. It features two taps at -5% FCBN for voltage adjustment and a 70A wiring connection. The enclosure is designed for indoor-outdoor use with a NEMA 3R rating.
Yes. Designed for Class I Division 2 hazardous locations (Groups C and D), this encapsulated transformer reduces ignition risk and simplifies regulatory compliance in oil & gas, chemical processing, and other high-risk environments, while providing robust voltage conversion from 480 V to 208Y/120 V for downstream equipment.
The Z48G28T15A is UL Listed and supports hazardous-location requirements Class I Division 2 (Groups C and D). It features a NEMA 3R enclosure suitable for indoor-outdoor installations, ensuring safe operation across varied environmental conditions and helping streamline site approvals and maintenance planning.
The encapsulated design and rugged construction reduce maintenance frequency and downtime in harsh environments. The warranty covers one year from installation or eighteen months from shipment, whichever occurs first, providing a clear baseline for cost of ownership and service planning.
