Allen-Bradley 1492-CB3G020 Three-Phase Circuit Breaker

Allen-Bradley 1492-CB3G020 is a three-pole energy-limiting miniature circuit breaker in the 1492-CB3 family, rated at 2 A to protect three-phase circuits in industrial control panels. The G-trip inductive characteristic indicates the breaker is designed to interrupt overloads on inductive loads, such as motors and transformers, helping to prevent equipment damage from short circuits and overloads. This 3P device is used in motor-control applications and serves as the protective element across all three phases of a circuit, enabling simultaneous interruption if current exceeds its rating. With a 2 A rating across three poles, it trips to safeguard conductors and connected equipment while maintaining coordinated protection in multi-phase systems; it is part of the Bulletin 1492 lineup and can function as a supplementary protector in appropriate assemblies. When selecting this breaker, ensure compatibility with your system voltage, wiring gauge, and panel design in accordance with Rockwell Automation’s 1492-CB documentation and the specific 1492-CB3G020 data for trip characteristics and mechanical fit.
