Allen-Bradley 800MR-QT24K Pilot Light

Allen-Bradley 800MR-QT24K Pilot Light is a 24-volt, full-voltage push-to-test indicator within the 800MR family, designed to serve as a visual status light in Allen-Bradley control panels. It illuminates when the associated circuit is energized, providing immediate indication for operators and technicians. The QT designation confirms push-to-test operation for quick verification of circuit status without powering down equipment. The unit is suited for 24 V AC/DC control circuits and integrates with standard 800MR mounting hardware in panel assemblies. Typical applications include signaling machine state or fault conditions on local control stations, motor starters, and safety interlocks, where reliable illumination enhances troubleshooting and operator awareness. As part of the 800MR line, it shares the family’s rugged construction and compatibility with other 800MR indicators and accessories, enabling consistent panel design across multiple stations and devices.
