Allen-Bradley 855TC-B10D3 Tower Stack Light Assembly

Allen-Bradley 855TC-B10D3 Tower Stack Light Assembly is a configured stack light signaling device from Rockwell Automation designed for mounting on a 25 mm diameter tube, featuring a 70 mm outer-diameter black housing with a cap-equipped base for quick installation. This 120 V AC full-voltage assembly is IP65-rated (NEMA 4X), providing protection against dust and water exposure in demanding factory environments. As part of the 855 Tower Stack Light family, the unit is built to deliver multi-level visual signaling, with Level-1 lens color Green enabling immediate status visibility; the configuration can be ordered pre-assembled to speed integration or configured from separate light modules for customization. Typical applications include signaling machine status and process readiness on manufacturing lines, packaging equipment, and other industrial automation cells where clear, instantaneous indication is required.
