Eaton Specification Sheet - ND27D92BCU
Feature → Business Impact → Application: K-Factor nonlinear design targets harmonic distortion generated by nonlinear loads, reducing voltage distortion and transformer heating; this yields higher reliability and longer life for drive-controlled equipment. In practice, this means less nuisance tripping and cooler operation in medium-to-heavy duty lines. Application: suitable for conveyors, robotics cells, and CNC-driven machinery where power quality matters. Feature → Business Impact → Application: Ventilated cooling provides superior heat dissipation for high-load operation, enabling an 80°C rise rating to be sustained under peak demand; result is stable voltage regulation and reduced thermal degradation. In manufacturing environments with limited cabinet cooling, this can simplify enclosure design and improve uptime. Application: drives and motors in hot or confined spaces benefit from this cooling strategy. Feature → Business Impact → Application: A 27 kVA rating supports mid-size three-phase loads with isolation between supply and equipment; delta-wye configuration (460V delta primary to 460Y/266V secondary) offers flexible motor starter compatibility and safer fault isolation. Benefit is easier panel integration and fewer voltage mismatches. Application: machine tools, packaging lines, and material handling systems that require robust drive isolation. Feature → Business Impact → Application: The transformer’s rugged construction, including a 467 lb weight, provides vibration resistance and durable mounting in industrial panels; compatibility with common frame mounting and cabinet spaces simplifies installation and serviceability. This also supports longer service life with fewer field replacements. Application: retrofits and new builds in automation cells with frequent maintenance. Feature → Business Impact → Application: Access to Eaton catalogs and datasheets expedites installation planning, wiring schematics, and compliance checks; teams can validate compatibility with existing drives and control panels before procurement. Benefit is reduced lead times, improved install quality, and predictable startup. Application: new builds and retrofits across automotive, packaging, and material handling lines.

FAQs
Plan for a three-phase 460V input with a delta primary and a 460Y/266V secondary, ensuring adequate clearance and ventilation. Position the unit to maximize airflow and minimize hot-spot buildup; use proper mounting hardware and follow Eaton’s wiring diagrams and enclosure guidelines from the spec sheet for safe, compliant installation.
Yes. The K-Factor nonlinear design specifically targets harmonic distortion, reducing harmonic currents and improving transformer efficiency under nonlinear loading. This supports safer operation of drives, conveyors, and motors while maintaining voltage integrity and reducing overheating risks.
Ideal for drive-intensive applications such as material handling, packaging lines, robotics cells, and CNC-based tooling. The 27 kVA rating, three-phase configuration, and isolation between supply and equipment provide robust power quality and protection for critical automation assets in busy plants.
Certifications are typically provided by the manufacturer; contact Eaton for current CE markings, UL/CSA recognition, IP ratings, and SIL documentation if applicable. Refer to Eaton’s specification sheets and catalogs to confirm the exact compliance package for your region and project requirements.
By reducing heat stress and harmonic-related losses, this transformer can lower cooling requirements, extend drive life, and reduce unplanned downtime. Access to Eaton datasheets and installation guides supports faster commissioning and fewer field changes, delivering a measurable return through improved uptime and energy efficiency in drive-heavy lines.
