Allen-Bradley 1497D-A14-M21-0-N Single-Phase Transformer

Allen-Bradley 1497D-A14-M21-0-N is a Gen Purpose, single-phase transformer rated at 3.0 kVA with a 480 VAC primary (60 Hz) and a dual secondary delivering 120/240 VAC in a delta configuration, making it suitable for control-power needs inside industrial automation panels. It ships without primary or secondary fuse blocks and has no taps, indicating a fixed-output design that is wired directly into control power networks for PLCs, relays, contactors, and other control components. Manufactured by Rockwell Automation (Allen-Bradley) in Mexico, this transformer is designed for rugged environments where dependable power conversion is needed in control panels, motor-control centers, or automation systems. At full loading, the 3.0 kVA rating corresponds to up to about 25 A at 120 V or 12.5 A at 240 V on the secondary windings.
