Allen-Bradley 800H-QRT24A Push Button Momentary

Allen-Bradley 800H-QRT24A is a 30.5 mm illuminated momentary pushbutton from the 800H family, engineered for 24 V AC/DC operation with a built-in incandescent pilot light and push-to-test capability. The device features a 1 NO-1 NC contact arrangement and is offered with a plastic operator cap for a compact, front-panel installation. Built for Type 4/4X/13 environments, it supports a full-voltage supply and is designed for panel mounting with standard 30 mm cutouts. The QRT variant integrates a push-to-test mechanism, enabling a quick status check without powering other circuit elements, and the internal lamp provides a clear visual indication of its energized state. Typical applications include control stations on industrial machinery, start/stop interlocks, and signaling circuits where a momentary input is combined with an indicator light. This model is identified by the part number 800H-QRT24A and is compatible with Rockwell Automation’s 800H mounting accessories, ensuring reliable operation in demanding environments.
