Allen-Bradley 800T-H48B30 USNT AC Servo Motor

Allen-Bradley 800T-H48B30 USNT is a 30 mm panel-mount selector switch in the 800T family, not a servo motor. This two-position device uses a standard cam and is supplied without guards on the terminals, enabling straightforward wiring in compact control enclosures. The contact block is a normally open/normally closed (1 NO, 1 NC) arrangement per position, providing simple start/stop or on/off signaling in automation circuits. The variant features spring return to the right and a left-side lock, supporting momentary or latched operation depending on the actuator configuration. With its robust construction for industrial environments, it’s commonly used in machine control panels, conveyors, and process-control stations where reliable manual control is required. The 800T-H48B30 can be paired with standard 800T accessories and mounting hardware within Allen-Bradley’s 30 mm push-button ecosystem, and is widely stocked by Rockwell Automation and authorized distributors for easy replacement and maintenance.
