Allen-Bradley 800T-QTH10R Push-To-Test Pilot Light

Allen-Bradley 800T-QTH10R is a 30.5 mm panel-mount pilot light in the 800T Push-To-Test family, featuring red LED illumination and a 120V AC operating voltage. The LED indicator is activated via a push‑to‑test control, allowing quick verification of lamp function without energizing the downstream circuit. Designed for standard 30.5 mm mounting cutouts used with 800T devices, it serves as a compact status indicator in control panels, machine interfaces, and process equipment. Within the 800T family, LED configurations offer flexible wiring options, including transformer/dual-input variants, to match diverse panel wiring schemes. Common applications include signaling machine status, fault indication, and readiness cues in industrial environments where durable, visibility-critical indicators are essential.
