FAQs
This unit is designed for indoor installation in power distribution panels. Ensure adequate clearance for ventilation not required due to the totally enclosed design, plan for the footprint (19.5 in D, 22.59 in W, 37.53 in H), and provide proper mounting hardware. Verify compatibility with 480 V primary and 60 Hz service, and ensure the panel enclosure can accommodate the 15 kVA rating with appropriate protection and wiring clearances.
The 15 kVA rating supports moderate power distribution for control cabinets and small machine loads. The taps at +2.5% FCAN and -2.5% FCBN enable precise voltage regulation to maintain stable voltage at sensitive equipment, reducing flicker and voltage-related faults. This configuration is particularly beneficial for PLCs, servo drives, and instrumentation panels where voltage stability matters.
Yes. The single-phase, DS-3 dry-type design is well-suited for indoor control panels and machine interfaces in manufacturing. The aluminum windings offer good thermal performance and durability, while the enclosed housing minimizes dust ingress and maintenance. Its footprint and mounting dimensions align with common enclosure layouts, supporting straightforward integration in existing or new panels.
Certifications vary by installation and region. Eaton provides certification details upon request and can furnish DS-3 design documentation, safety data, and catalog references as needed. For regulated environments, specify your jurisdiction to obtain UL, CE, or other compliance documentation where applicable.
Maintenance is typically lower with a totally enclosed non-ventilated, dry-type transformer due to sealed windings and no external cooling fans. The 15 kVA rating supports efficient, reliable operation in end-user equipment, and the one-year warranty (or 18 months from shipment) provides protection against early-life defects. Over the life of the unit, reduced dust ingress and fewer vent-related failures translate to lower downtime and favorable total cost of ownership.
