Allen‑Bradley 1497‑B‑BASX‑3‑N is a single‑phase control circuit transformer rated for 80 VA, designed to power low‑voltage control circuits from higher‑voltage mains. Its primary voltage options are 240/480 VAC at 60 Hz or 220/440 VAC at 50 Hz, with a secondary delivering 110 VAC (50 Hz) or 120 VAC (60 Hz). The unit features a 2‑primary / 1‑secondary fuse block arrangement and ships with no cover and no secondary fuse in the standard configuration. Dimensions are 3.5 in wide, 2‑3/8 in high, and 3‑7/8 in deep, and it weighs about 4.5 lb, with copper conductors used for the windings.
