Feature → Business Impact → Application: Class 1 Division 2 encapsulated design provides a robust barrier against dust, moisture, and potential ignition sources, significantly reducing the risk of hazardous-area incidents and downtime. Benefit: enhanced safety and compliance lead to lower insurance costs and fewer relocation or shutdown events in critical process lines. Application: chemical plants, oil and gas facilities, and other hazardous environments where reliable power is essential. Feature → Copper windings with 30 kVA rating deliver high efficiency and low copper loss, improving overall energy utilization and reducing operating costs. Application: plant power feeds and motor-control centers that demand steady voltage conversion with minimal heat generation. Feature → Primary 480 V and secondary 208Y/120 V, three-phase configuration at 50/60 Hz, enables seamless integration with common facility distributions. Benefit: simplifies design, reduces interconnection complexity, and supports universal compatibility across equipment fleets. Application: retrofit projects and new builds in manufacturing facilities where standard voltage levels are required. Feature → EPTZ design and frame 244H provide rugged mechanical protection and proven performance in harsh environments. Benefit: extended service life and easier stocking of replacement parts. Application: installations with frequent thermal cycling or harsh ambient conditions. Feature → Tap size 2 at -5% FCBN offers voltage adjustment to maintain output under supply fluctuations. Benefit: precise voltage regulation reduces equipment stress and improves process stability. Application: utilities and process industries exposed to variable incoming voltages. Feature → Weathershield indoor-outdoor enclosure with 66A wiring connection supports flexible mounting and long-term durability. Benefit: simpler installation with fewer enclosure constraints and improved protection against environmental ingress. Application: indoor installations adjacent to process lines or outdoor sites with sheltered exposure. Feature → 80 °C rise rating ensures thermal performance under full-load conditions. Benefit: reliable continuous operation and predictable thermal margins for critical loads. Application: continuous operation feeders powering sensitive equipment and control systems. Feature → 30 kVA VA rating aligns with moderate-to-heavy power distribution needs. Benefit: scalable for expanding plants and variable load profiles, reducing the need for oversized cabinets. Application: motor-starting circuits and feeder transformers in medium-duty automation lines. Context: All features are backed by Eaton’s catalog and datasheet guidance, with warranty terms of one year from installation or eighteen months from shipment, whichever occurs first, reinforcing long-term support and serviceability.

FAQs

The Z48G28B30CU is designed for Class I Division 2 environments with encapsulated protection, providing a safe and compliant power solution for hazardous areas. Verify site-specific approvals (UL/CSA/CE) with Eaton to ensure all regional certifications align with your facility requirements. Proper mounting, clearances, and protective enclosures are recommended to maximize safety margins.
Key specs include 30 kVA VA rating, 480 V primary, 208Y/120 V secondary, three-phase configuration, and a 50/60 Hz frequency rating. Copper windings and an 80 °C rise support reliable performance under full load. The tap changer is 2 taps at -5% FCBN, enabling voltage adjustments to accommodate supply variations.
The unit is rated indoor-outdoor, with a 66A wiring connection and an EPTZ design in a 244H frame, making it suitable for flexible mounting in diverse facilities. Ensure adequate ventilation, proper enclosure protection, and compliance with local electrical codes. The 80 °C rise rating indicates solid thermal performance under load, reducing the risk of overheating in harsh environments.
Warranty terms specify one year from the date of installation or eighteen months from the date of shipment, whichever occurs first. For extended coverage or specific service-level agreements, consult Eaton’s Selling Policy and your authorized Eaton distributor to tailor a maintenance plan aligned with your plant’s uptime requirements.
Typical applications include chemical plants, oil and gas facilities, and other hazardous zones requiring reliable, safe power conversion.
