Overview
The Allen-Bradley 800T-A1A is a 30.5mm (30mm) momentary green pushbutton operator designed for industrial automation and control station integration. This Bulletin 800T Series device delivers dependable switching performance in NEMA 4/13 (Type 4/13) watertight and oiltight enclosures. With a flush head profile and integrated contact blocks, the 800T-A1A serves as a standard workhorse in machine tool panels, production lines, and process control systems where reliability is critical.
Key Features
- 30.5mm mounting hole size—standard industrial footprint for panel integration
