Allen-Bradley 800T-A2A Electronic Time Delay Relay

Allen-Bradley 800T-A2A is a 30 mm panel-mount pushbutton from the rugged 800T family, designed for industrial control panels. The flush black head and 30 mm footprint provide a low-profile operator ideal for crowded enclosures, while delivering reliable actuation in harsh factory environments. This model uses a SPDT contact arrangement—one normally open (NO) and one normally closed (NC)—allowing simple start/stop logic or two-signal control from a single device. It is a momentary pushbutton, returning to its resting position after actuation, which makes it suitable for momentary-start functions, interlock sequences, or reset actions in process and packaging lines. The 800T-A2A is intended for panel mounting in standard 30 mm cutouts, aligning with common field-installation practices and replacing legacy components with minimal panel modification. As part of Allen-Bradley’s 800T pushbutton line, it provides consistent electrical characteristics and a familiar tactile feel across 800T operators, aiding maintenance and stocking in multi-station panels.
