Eaton V48M22T15EEZZ Open core-coil ventilated transformer - UL Recognized
Part Number: V48M22T15EEZZ
Quick Summary
Open core-coil ventilated transformer from Eaton delivers 15 kVA three‑phase power for commercial and industrial distribution. Many plants struggle with overheating, tap mismatch, and inconsistent voltage under peak load. UL Recognized and NEMA TP-1 compliant, with open‑type core and coil assembly, support safe operation and regulatory alignment. As a dry‑type distribution transformer, it simplifies installation and supports stable 240/120 midtap for secondary circuits, helping reduce downtime and energy waste with 60 Hz operation. This makes it an ideal choice for control panels, machine feeders, and facility distribution.

Open core-coil ventilated design provides superior cooling and thermal management, enabling the 150 °C rise rating to sustain peak loads without derating. Business impact: greater uptime and reliability in harsh industrial environments; Application: used in 3‑phase 480 V to 240/120 distribution networks. Tap options of 2 at +2.5% and 4 at -2.5% plus a 240 delta/120 midtap allow precise voltage regulation, reducing equipment stress and improving drive and control performance in variable supply conditions. Business impact: tighter voltage control translates to fewer nuisance tripping events; Application: control panels, motors, and lighting circuits in manufacturing facilities. With 60 Hz operation and UL/NEMA TP‑1 certifications, compliance is streamlined and installation is straightforward. Application: US-based facilities prioritizing safety and regulatory alignment. Aluminum coil construction and a robust 912B frame support durable, serviceable installations, aiding maintenance planning and lifecycle cost reduction. Business impact: lower replacement costs and easier field upgrades. Warranty and service policies (one year from installation or eighteen months from shipment) provide predictable total cost of ownership and reliable vendor support. Application: asset management programs in process and discrete manufacturing.

FAQs
The V48M22T15EEZZ is a 15 kVA three‑phase dry‑type transformer designed for installation in standard electrical rooms or equipment cabinets. With a 189 lb weight and a 912B frame, it supports straightforward mounting and serviceability. It also benefits from an open core‑coil ventilated design that requires adequate clearance for airflow and compliance with UL and NEMA TP‑1 installation practices.
The transformer provides taps at +2.5% and -2.5% and a 240 delta/120 midtap, enabling voltage regulation to compensate for line fluctuations. By selecting the appropriate tap, you can maintain stable secondary voltage under varying loads, reducing equipment stress and improving performance in control panels, drives, and lighting circuits.
Yes. The V48M22T15EEZZ is UL Recognized and NEMA TP‑1 compliant, reflecting safety, efficiency, and installation standardization for commercial and industrial power distribution. This certification simplifies procurement when regulators or customers require documented compliance and supports risk management for critical infrastructure projects.
Its 480 V primary and 240/120 secondary output suit machine rooms, panel boards, and distribution networks in manufacturing, packaging, and process industries. The dry‑type, open‑core design improves cooling in confined spaces, while the 60 Hz, three‑phase configuration aligns with typical US power systems and helps consolidate multiple feeders into a single, reliable transformer asset.
Warranty terms follow Eaton policy: one year from installation or eighteen months from shipment, whichever occurs first. For service, you can rely on Eaton support and the documented catalog notes for maintenance practices, efficiently replacing or recalibrating taps, and ensuring continued compliance with NEMA TP‑1 and UL recognized standards.
