Allen-Bradley 812S-AOC5 Industrial Circuit Breaker

Allen-Bradley 812S-AOC5 Industrial Circuit Breaker is a Rockwell Automation bulletin-style protection device from the 812S family. This 600 V, three-phase breaker is designed for AC power systems operating at 50 or 60 Hz and is cataloged as Series A (812S-AOC5; sometimes listed as 812SAOC5). It provides overcurrent protection for electrical feeders and machine circuits in industrial environments and is designed for use with legacy Allen-Bradley control panels and distribution gear, offering a familiar form factor and wiring scheme for retrofits or ongoing installations. As part of the Allen-Bradley circuit protection lineup, this model supports standard 50/60 Hz industrial networks and is deployed in settings where robust protection and reliable interruption of fault currents are required in three-phase electrical systems. This model is part of Rockwell Automation's Allen-Bradley catalog, reflecting the brand’s long-standing emphasis on reliable industrial protection components.
