Allen-Bradley 800T-QBL10GD1 30 mm Pilot Light

The Allen-Bradley 800T-QBL10GD1 is a 30.5 mm full-voltage incandescent pilot light with a blue Fresnel lens and a 120 VAC illumination module, providing a clear visual indication of machine and process status in heavy-duty control systems. Built on the Bulletin 800T platform, this round 30.5 mm NEMA operator device uses a metal enclosure and screw-terminal wiring for rugged service in motor control centers, operator stations, industrial control panels, and manufacturing equipment, with oil-tight sealing for demanding environments. It carries UL Listed, CSA Certified, CE, CCC, and EAC certifications, and is rated for enclosure protection of NEMA 1, 4, 12, and 13, plus 10 G vibration and 100 G shock resistance; operating temperature starts at -25°C and storage at -40°C. It is used to indicate machine operation, system status, process conditions, and alarms in packaging machinery, conveyors, material handling equipment, water and wastewater facilities, process plants, and factory automation systems, and is a common choice for OEM replacement, control panel assembly, retrofit projects, and industrial automation maintenance—often by system integrators. Common replacements include Allen-Bradley 800T-Q10B, 800T-QT10B, and 800TC-Q10B.
