Feature: Encapsulated transformer with EPTZ design provides robust protection in Class 1 Division 2 environments. Business Impact: Reduces ignition risk and simplifies regulatory approvals, accelerating safe installations. Application: Ideal for control power in hazardous-area cabinets and outdoor enclosures without compromising safety. In practice, this design translates to fewer field modifications and faster commissioning in chemical processing plants. Feature: Aluminum windings offer corrosion resistance and lighter weight. Business Impact: Easier handling during installation, reduced structural support requirements, and lower ongoing maintenance costs. Application: Suitable for harsh industrial sites where moisture or pollutants are present, improving long-term reliability. Feature: Three-phase 15 kVA rating with 480 V primary and 220Y/127 V secondary. Business Impact: Streamlines power distribution by delivering controlled voltage to plant controls and auxiliary equipment with minimal voltage drop. Application: Powering motor starters, PLCs, and control panels across production lines. Feature: Tap changers at 2 positions (-5% FCBN). Business Impact: Maintains voltage regulation under varying load, reducing equipment stress and nuisance trips. Application: Critical for PLC inputs and sensitive sensors in fluctuating electrical environments. Feature: NEMA 3R enclosure with Indoor-Outdoor Weathershield. Business Impact: Enables flexible installation options, including exterior or semi-exposed locations, while preserving enclosure integrity. Application: Outdoor control rooms, weather-protected cabinets, and harsh plant floors. Feature: UL Listed certification and 1-year (or 18 months from shipment) warranty. Business Impact: Assurance of compliance and strong vendor support, lowering procurement risk. Application: Relevant across process industries, where regulatory compliance and service continuity matter for ROI and total cost of ownership.

FAQs
The Z48G31T15 is designed for Class 1 Division 2 Groups C and D environments with a NEMA 3R enclosure suitable for indoor-outdoor use. When installing, ensure proper clearance for ventilation, follow local electrical codes, and coordinate with the cabinet or cell layout to accommodate its 25.18 in width, 17.78 in height, and 10.52 in depth footprint. The unit’s aluminum windings and -5% tap option aid voltage stability under load without additional external equipment.
Key specs include three-phase operation at 50/60 Hz, a primary voltage of 480 V, a secondary of 220Y/127 V, and a 15 kVA VA rating. The transformer uses aluminum windings, has a frame of 95H, and offers two taps at -5% FCBN. It features a 115 °C temperature rise and a 70 A wiring connection rating, with indoor-outdoor Weathershield and a NEMA 3R enclosure.
Yes. The Z48G31T15 combines a NEMA 3R enclosure with indoor-outdoor suitability and a hazardous-location design (Class 1 Division 2). Its rugged aluminum windings, compact footprint, and 15 kVA rating support reliable power to control panels, PLCs, and instrumentation in outdoor or semi-exposed areas, while maintaining compliance and safety standards.
The transformer is UL Listed, provides Class 1 Division 2 hazardous location compatibility (Groups C and D), and uses a NEMA 3R enclosure suitable for indoor-outdoor installations. This combination supports regulatory compliance, field acceptance, and safer operation in hazardous environments, reducing qualification time for safety audits and enabling smoother procurement.
Eaton provides a one-year warranty from installation or eighteen months from shipment, whichever occurs first, with UL Listed certification. This warranty, combined with durable construction and low-maintenance design (aluminum windings, -5% tap, NEMA 3R enclosure), contributes to lower total cost of ownership by reducing replacement risk, maintenance intervals, and downtime in hazardous-location applications.
