Totally enclosed non-ventilated enclosure provides dust and moisture protection in harsh indoor environments; reduces maintenance and eliminates venting points that can allow contaminants to enter the enclosure, improving reliability in control panels and motor control centers. DS-3 dry-type design enhances safety and installation flexibility; no oil, minimal fire risk, and simplified compliance for indoor power distribution in commercial facilities. The 45 kVA rating with 400 V primary and 120/240 V secondary, plus 50-60 Hz operation and precise taps (+5% FCAN, -5% FCBN), enables fine-tuning to support variable loads and startup surges in industrial equipment. Aluminum windings and a robust 820N frame provide strong thermal performance and durability, helping reduce replacement costs in dense electrical rooms. Compact footprint and UL Listed certification streamline installation in new builds and retrofit projects while aligning with safety standards. Maintenance-friendly design and Eaton support reduce total cost of ownership, delivering predictable performance for power distribution in manufacturing lines, packaging, and automation systems.

FAQs
The T39R11S45XNV is designed for DS-3 dry-type installation in indoor electrical spaces. Mount it on a stable, level surface suitable for its 632 lb weight, ensure adequate clearance for cooling and access, and connect primaries and secondaries to standard busbar or terminal blocks compatible with 400 V and 120/240 V circuits. Use the +5% and -5% taps as required to compensate for voltage variation. Follow the UL Listed safety guidelines for enclosure integrity and grounding, and verify clearances per local codes. Proper sequencing during energization minimizes inrush effects on downstream equipment.
Key specifications to confirm include 45 kVA rating, single-phase configuration, 400 V primary voltage, 120/240 V secondary voltage, 50-60 Hz frequency rating, and a 150°C rise. The unit features aluminum windings, a frame 820N, and taps at 1 @ +5% FCAN and 2 @ -5% FCBN. It is UL Listed and designed for indoor, dust-prone environments. The product footprint (23.84 in L × 24.22 in W × 42.03 in H) should fit the intended space.
Yes. The T39R11S45XNV is a DS-3 dry-type distribution transformer with a compact footprint and robust enclosure, ideal for control panels, motor control centers, and machine cabinets. Its 45 kVA rating provides ample headroom for moderate loads, and the 400 V to 120/240 V secondary supports typical industrial equipment. The aluminum windings and 150°C rise rating contribute to reliable operation in continuous-duty applications with limited ventilation.
The primary certification highlighted for this transformer is UL Listed, which confirms safety compliance for industrial installation. The DS-3 design specifies a dry-type, enclosed configuration suitable for indoor use. While CE or IP ratings are not listed in the provided data, UL Listing provides a strong safety endorsement for electrical installations in North America.
This transformer carries Eaton’s standard warranty policy, offering one year from the date of installation or eighteen months from shipment, whichever occurs first. Its dry-type design inherently reduces maintenance costs by eliminating oil handling and reducing fire risk compared with oil-filled units. The aluminum windings and robust frame contribute to long service life, minimizing replacement frequency and supporting predictable total cost of ownership in automation and distribution applications.
