Sylvania 751-L03-3AN Transformer

The Sylvania 751-L03-3AN Transformer is a 7.5 kVA, three‑phase power transformer designed for 60 Hz electrical systems. It accepts a 460 V input and delivers a 230 V line‑to‑line secondary with a 133 V line‑to‑neutral (230Y/133 V) configuration, enabling stepped‑down power for three‑phase equipment from a higher‑voltage supply. Rated at 7.5 kVA, it supports moderate loads such as three‑phase motors, control panels, and other industrial hardware that require 230 V service derived from a 460 V input. The model number 751‑L03‑3AN identifies this specific variant within Sylvania's transformer lineup, which helps ensure exact fit when replacing a legacy part in compatible systems. In typical field configurations, the transformer provides reliable voltage conversion for distribution networks where 460 V is present on the primary side and downstream equipment operates at 230 V three‑phase, with an available 133 V phase‑to‑neutral for auxiliary circuits.
