FAQs
This transformer delivers 150 kVA with a 480 V primary and 208Y/120 V secondary in a three-phase configuration, making it well-suited for motor control centers and distribution boards. The wide enclosure footprint, aluminum windings, and 918A frame simplify mounting, while the +2.5%/ -2.5% taps support on-site voltage alignment to deliver stable operation in existing panel schedules.
The K-Factor nonlinear design is explicitly intended to mitigate harmonic currents, reducing hotspot risk and improving efficiency under non-linear loading. Coupled with a 150°C rise rating and electrostatic shielding, it maintains performance and minimizes voltage distortion in drives and power electronics commonly found in modern manufacturing and data centers.
Yes. It is UL Listed and NEMA TP-1 compliant, which confirms conformance to recognized safety and efficiency guidelines for low-voltage transformers. This alignment reduces risk during procurement and installation and supports regulatory expectations in commercial and industrial facilities.
Catalog notes indicate a low sound profile of 47 dB, which is favorable for occupied spaces. Weathershield WS34 is available for outdoor or harsh-environment applications. The unit weighs about 1,532 lb with dimensions of roughly 30.68 in long, 62.18 in high, and 31.44 in wide, affecting crane and mounting requirements during installation.
Eaton offers a warranty per policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. This warranty, combined with solid construction and standard maintenance practices, supports long-term reliability for mission-critical circuits in industrial environments.
