Allen-Bradley 1497-N5 USNT Limit Switch

The Allen-Bradley 1497-N5 is a dry-type control transformer designed to provide safer, isolated low-voltage power for industrial control circuits. It features a 480 VAC primary winding and a 120 VAC secondary winding, enabling machines and panel components to operate their relays, contactors, timers, and sensing devices from a readily available 480 V supply. As part of the 1497 transformer family, the N5 model is built for panel-mounted installations in industrial environments, delivering reliable control power without routing high-voltage through control circuitry. The unit is intended for use wherever a standard 480 V supply must be stepped down to 120 V for control circuits, offering a compact solution that minimizes wiring complexity in control panels. With its dry-type construction, the transformer is widely used in machine controls and process equipment to supply auxiliary power for safety interlocks, PLC input modules, and signaling devices. The 1497-N5 is one of Allen-Bradley’s classic control transformers that integrates into legacy and new equipment designed around 480 V primary voltages and 120 V control circuits.
