The Allen-Bradley 1497-E-BASX-3-N is a 250 VA control circuit transformer designed to power low-voltage control circuits from higher-voltage mains. It supports dual primary voltages: 240/480 V at 60 Hz or 220/440 V at 50 Hz, with a single secondary winding that provides 120 V for 60 Hz operation or 110 V for 50 Hz operation. The assembly includes two primary fuse blocks and one secondary fuse block to protect both sides of the transformer during operation.
