Allen-Bradley 700-HA33A1 USNT Relay is a General Purpose Tube-Base Relay from the 700-HA family. It uses a 120 V AC coil (50/60 Hz) and provides a 3PDT contact arrangement with a 10 A rating, designed for plug-in installation in standard 700-H tube-base sockets. This configuration supports switching three independent circuits from a single coil, making it suitable for compact control panels and automation circuits that require multiple throw paths. Catalog variants exist, such as 700-HA33A1-3-4-99, which include options like Push-To-Test and Pilot Light, but the core model remains a 3PDT, 10 A, 120 VAC coil relay.
