Allen-Bradley 1492-CB3 Three-Pole Circuit Breaker

Allen-Bradley 1492-CB3 Three-Pole Circuit Breaker (G050) is a Rockwell Automation protection device designed for three-phase circuits in industrial control panels. The G050 suffix specifies a 5 A rated version, and the 1492-CB3-G050 variant is marketed for DIN-rail mounting, enabling quick integration into standard enclosure layouts. The 1492-CB3 family is UL 508 and CSA 22.2 No. 14 listed for 3-phase applications, with current ratings available across a range of values to suit different loads. Common applications include protecting motors, conveyors, pumps, fans, and other three-phase equipment in manufacturing and process environments, where reliable interruption of fault currents helps safeguard conductors and devices. This unit provides a three-pole protective pathway within industrial power systems and should be matched to the exact suffix and mounting style required by the panel design, since the 1492-CB3 lineup encompasses multiple configurations beyond the G050 variant.
