Totally enclosed non-ventilated design provides dust protection and reduced cooling requirements, lowering maintenance costs and extending service intervals in dusty or confined spaces. The business impact is lower total cost of ownership and higher equipment availability, particularly in manufacturing floors and switchgear rooms where enclosure integrity matters. This unit uses copper windings in a dry-type construction, delivering oil-free operation that simplifies installation in indoor environments and improves safety during maintenance and servicing. The application is well-suited for control panels, machine tools, and distribution boards where oil-filled transformers are undesirable. A multi-tap primary and fixed secondary arrangement offers voltage flexibility to accommodate site variations, reducing the need for additional transformers and enabling smoother commissioning across different facilities. The 5 kVA rating at 60 Hz supports compact power distribution for panels and compact plant equipment, enabling scalable deployment. With a frame of 815N and dimensions of 15.82 x 16.87 x 30.25 inches and a weight of 205 lb, installation fits typical enclosure footprints while maintaining robust mechanical support. The unit’s temperature rise of 80 °C ensures dependable performance in moderate ambient conditions, and the 25-000 warranty window provides procurement peace of mind and service alignment with Eaton’s support framework. These features collectively translate into improved energy efficiency, regulatory compliance, and faster ROI for panel builders and OEMs.

FAQs
The T10P48B05CUNV supports a 120/240 V primary and a 480 V secondary. It features taps at 1 at +5% FCAN, 2 at -5% FCBN, and 2 at +2.5% FCAN with 4 at -2.5% FCBN, enabling voltage adjustments to match site conditions without additional equipment. Proper wiring and tap selection should follow the Eaton datasheet and site voltage surveys to ensure voltage regulation within the required tolerance.
Yes. The unit is a dry-type, copper-wound transformer with a totally enclosed non-ventilated design, which protects the windings from dust and moisture ingress and reduces cooling requirements. Its enclosure is intended for indoor panel boards and machine-control cabinets, contributing to safer operation and easier maintenance in manufacturing or processing environments.
Dimensions are 15.82 inches (length) by 16.87 inches (width) by 30.25 inches (height), with a weight of 205 pounds. The frame is 815N, facilitating mounting in standard electrical closets or equipment racks. When planning installation, verify enclosure clearance, ventilation strategy (if applicable), and adequate load support to ensure serviceability and safe conduit routing.
With copper windings and a dry-type design, maintenance emphasizes enclosure integrity, connection torque, and periodic insulation verification rather than oil management. Regular inspections should check for dust buildup, overheating indicators, and secure tap connections. The absence of oil reduces spill risk and simplifies compliance with indoor air quality and fire-safety standards.
The product carries Eaton’s warranty options: one year from installation or eighteen months from shipment, whichever occurs first, reflecting standard coverage for power transformers. Certifications are region-specific; contact the manufacturer for current compliance marks such as CE, UL, or CSA as applicable to your installation site and regulatory requirements.
