EE71H45S

Overview

The SolaHD EE71H45S is a 45 kVA general purpose dry-type isolation transformer. It features a primary voltage rating of 600V Delta and a secondary voltage rating of 480Y/277V Wye. Designed for industrial and commercial power distribution, this unit provides electrical isolation to enhance system safety and reduce noise. The construction supports standard environmental conditions typical for indoor installation in facilities requiring reliable voltage transformation and power quality management.

Feature Summary

• Provides electrical isolation between primary and secondary circuits
• Designed for general purpose industrial and commercial power distribution
• Dry-type construction suitable for indoor environments

Applications

• Industrial power distribution systems
• Commercial building electrical infrastructure
• Voltage transformation from 600V to 480Y/277V networks

Procurement Notes

Verify the specific voltage configuration matches the site requirements, as the model denotes a 600D-480Y connection. Confirm that the ambient temperature and ventilation conditions align with the manufacturer's specifications for dry-type transformers. Ensure the physical dimensions and weight are accounted for during installation planning. Cross-reference the serial number and manufacturing date if lifecycle support is required.

Selection Notes

Select this component when a 45 kVA capacity is required for stepping down or isolating 600V Delta sources to 480Y/277Wye loads. Consider the dry-type construction for indoor applications where liquid cooling is not feasible. Evaluate the short-circuit withstand capabilities against the available fault current at the installation point. Ensure the enclosure type meets the environmental protection needs of the specific deployment location.

Part Context

This transformer belongs to the SolaHD EE71 series, which focuses on general purpose isolation solutions. The brand is associated with Emerson's power quality portfolio, offering products for industrial environments. This specific model addresses common voltage levels found in North American industrial facilities, providing a standardized solution for power distribution tasks.

Replacement Considerations

Consult official SolaHD documentation for direct cross-references. Verify that any substitute maintains the exact 45 kVA rating and 600D-480Y vector group. Ensure physical footprint and terminal configurations are compatible with existing busbar or cable connections without modification.
