Square D 250SV1B General Purpose Transformer

Square D 250SV1B General Purpose Transformer is a compact, encapsulated dry‑type transformer that delivers 0.25 kVA of power in a single‑phase package. It is rated for dual primary voltages of 240/480 VAC and dual secondary voltages of 120/240 VAC, enabling you to feed 120/240 V control circuits from a 240 or 480 V supply in commercial and industrial panels. The unit is designed for general‑purpose use, with a 60 Hz operating frequency and Trade Agreements Act (TAA) compliant construction for procurement. Its enclosure footprint is roughly 5.5 inches tall, 5.23 inches wide, and 4.06 inches deep, aiding compact mounting in space‑constrained panels. The model number is 250SV1B from Square D (Schneider Electric), part of the brand’s general‑purpose, low‑voltage distribution transformer family. This transformer is suitable for applications such as control circuits and lighting where a 120/240 V secondary is required from a higher‑voltage source, with a dry‑type encapsulated design that requires no oil and supports straightforward installation in electrical panels and equipment racks.
