Schneider Electric 250SV1B General Purpose Transformer

Schneider Electric’s Square D 250SV1B is a 0.25 kVA, single‑phase general‑purpose transformer that accepts a dual primary input of 240 V or 480 V and delivers a center‑tapped 120/240 V secondary. This encapsulated, dry‑type unit is designed for reliable use in control panels and power distribution, with a 60 Hz operating frequency and a 55°C temperature rise that is listed as TAA compliant. Housed in a NEMA 3R enclosure, the 250SV1B is compact enough for wall‑mount or panel‑mount installations, with approximate dimensions of 5.5 in (H) × 5.23 in (W) × 4.06 in (D). Typical applications include powering 120/240 V control circuits, relays, sensors, and instrumentation from higher distribution voltages (240/480 V) in HVAC equipment and building automation systems.
