Eaton T48M11S15NV Transformer - 150C Rise, 15 KVA
Part Number: T48M11S15NV
Quick Summary
The Eaton T48M11S15NV transformer provides reliable isolation and stepping down for 480-120/240V systems in rugged industrial environments. Many facilities struggle with heat buildup and footprint when selecting power transformers. Certifications vary by region and installation; confirm UL/CE listings and enclosure IP ratings with the manufacturer. This 15 kVA, single-phase transformer delivers compact installation, low maintenance, and robust performance for control panels and small substations. Choosing a non-ventilated enclosure reduces fan noise, simplifies retrofits, and improves reliability in harsh industrial settings. With a 150°C rise rating and 327 lb weight, the T48M11S15NV handles demanding duty cycles while protecting critical downstream equipment. As you scale your power distribution, this transformer supports reliability, compliance readiness, and total cost of ownership reductions.

FAQs
The T48M11S15NV is designed for single-phase 480 VAC input with a 120/240 VAC secondary, making it well-suited for control panels, machine centers, and compact electrical rooms. Its totally enclosed non-ventilated (TENV) enclosure helps protect windings from dust and moisture, while the 15 kVA rating supports a range of automation and control loads. When retrofitting, verify cabinet space, mounting hardware, and clearance for cooling and wiring. Consult Eaton datasheets for exact mounting patterns and recommended conductor sizes.
Key specs include a 15 kVA rating, single-phase operation, primary voltage of 480 VAC, and secondary voltage of 120/240 VAC. The enclosure is totally enclosed non-ventilated, with a 150°C rise rating, and the unit weighs about 327 pounds. The catalog number is T48M11S15NV, and the UPC is 786680141928. These details guide wiring schemes, protection settings, and installation clearances in panel builds.
The T48M11S15NV uses a robust TENV enclosure designed for dust and moisture control in industrial spaces. Certifications for this product are listed as Contact Manufacturer, so regional UL/CE markings and IP ratings should be confirmed with Eaton during procurement to ensure compliance with local codes and customer requirements.
Thanks to the totally enclosed non-ventilated design, maintenance intervals are extended due to reduced dust ingress and fewer moving parts. The unit’s simple single-phase construction minimizes fault modes, contributing to lower lifecycle costs. Routine checks should include terminal integrity, enclosure seals, and thermal protection circuit verification, aligned with Eaton’s datasheet recommendations.
With a 15 kVA rating in a compact, rugged package, this transformer reduces the need for multiple smaller devices, saving floor space and simplifying wiring. The non-ventilated design lowers cooling requirements and maintenance, while the enclosure provides protection in demanding environments. These factors translate to improved uptime, easier compliance qualification, and overall total cost of ownership reductions for automation or packaging lines.
