Selling Policy 25-000 - Distribution and Control Products and Services
The totally enclosed non-ventilated design minimizes dust ingress and reduces cooling requirements, lowering maintenance costs and extending service intervals, which translates to less downtime in harsh industrial spaces. Copper windings and high-grade insulation improve energy transfer efficiency and reduce operating losses, delivering cooler operation and long-term energy cost savings. The DT-3 dry-type construction with a 37.5 kVA rating and 916AN frame provides a compact footprint, enabling easier installation in crowded switchgear rooms while maintaining robust thermal performance. With a 480 V primary and 208Y/120 V secondary, plus taps at +5% FCAN and -5% FCBN, on-site voltage adjustments accommodate load variations and distribution tolerances, reducing voltage-related equipment stress. Three-phase, 60 Hz operation aligns with standard North American power systems, delivering predictable performance and simplified engineering. A 150°C rise rating gives insulation margin for hot plant environments, helping maintain reliability under peak loads. The copper coil construction and UL Listed certification reinforce durability and safety, while Eaton’s warranty policy (one year from installation or 18 months from shipment) provides risk mitigation for ongoing operations. Dimensions and weight (23.42 in L, 28.22 in W, 32.02 in H; 907 lb) support accurate space planning and mounting considerations in existing enclosures. Industry insight confirms that adopting a rugged, enclosed transformer reduces dust-related failures and accelerates compliance reporting in heavy industrial facilities.

FAQs
For placement, allow adequate clearance around the 23.42 inch by 28.22 inch footprint and 32.02 inch height to accommodate service access, taps, and thermal management. Mount on a stable surface capable of supporting approximately 907 pounds, and ensure the enclosure remains environment-appropriate for dusty or harsh conditions. Verify local codes and UL compliance during setup.
This transformer delivers 37.5 kVA with a 480 V primary and 208Y/120 V secondary at 60 Hz in a three-phase configuration. Copper windings support efficient operation, and a 150°C rise rating provides insulation margin. Taps at +5% FCAN and -5% FCBN allow field voltage adjustments to accommodate load changes without external equipment.
Yes. Its totally enclosed non-ventilated design minimizes dust and moisture ingress, enabling reliable operation in dusty or hot spaces without external cooling. UL Listed certification confirms safety compliance, while the DT-3 dry-type construction supports robust performance in demanding facilities such as manufacturing floors and processing plants.
Eaton provides a warranty policy of one year from installation or eighteen months from shipment, whichever occurs first. Comprehensive documentation includes the UL Listed status and datasheets (Eaton Specification Sheet for V48M28T37CUNV) and catalog references, which help with compliance, maintenance planning, and asset records.
The unit features a 480 V primary and 208Y/120 V secondary with taps at +5% FCAN and -5% FCBN, enabling on-site voltage compensation to maintain stable secondary voltage under varying load. This capability minimizes voltage drop across distributions, reduces stress on downstream equipment, and simplifies integration with existing switchgear and protection schemes.
