Allen-Bradley 1492-CB2G500 Energy Limiting Circuit Breaker

Allen-Bradley 1492-CB2G500 Energy Limiting Circuit Breaker is a two-pole miniature breaker from the 1492 Energy Limiting family designed for industrial control panels and power-distribution applications. This 50 A device uses a G-curve (inductive-load) with a magnetic trip range of about 6 to 10 times the rated current, enabling rapid interruption of fault currents and reducing let-through energy. It is intended for AC systems up to 480 VAC (50/60 Hz) and employs screw-terminal connections for secure wiring. As part of the 1492 wiring system, it protects feeders and control circuits while delivering energy-limiting performance that minimizes conductor and downstream equipment damage during faults. The model is compatible with DIN-rail mounting configurations typical of 1492 devices and carries approvals such as UL 508 and CSA, reflecting its suitability for compliant industrial environments. In summary, the 1492-CB2G500 provides reliable two-pole protection with precise current limiting for inductive loads, making it a targeted choice for machinery panels and control cabinets where fast fault interruption and durable endurance are essential.
