Allen-Bradley 800H-QR10 Industrial Pilot Light

The Allen-Bradley 800H-QR10 is a 30.5 mm full-voltage incandescent pilot light that provides a clear visual indication of machine and process status in industrial control systems. It ships without a lens (UNMP), allowing a color lens to be installed separately to meet specific requirements, with options such as amber, red, green, blue, or clear when paired with compatible lenses. Designed for rugged industrial environments, it accepts 120 VAC or DC input, uses screw-terminal wiring for 14–18 AWG conductors, and requires a 30.5 mm mounting hole; it features a NEMA enclosure rating of 1, 4, 4X, 12, 13 and a Class I, Division 2 hazardous location rating, with operating temperatures down to -25°C and storage down to -40°C. Commonly installed in motor control centers, operator stations, industrial control panels, and manufacturing equipment to indicate machine operation, power status, alarms, or process conditions, and it is compatible with Bulletin 800H operator devices. Common replacements include the Allen-Bradley 800H-QR10A, 800HC-QR10, and 800H-QR24.
