Product Description
The Allen-Bradley 140G-N6I3-E12-Z1 circuit breaker, an N-frame device weighing 21.39 pounds, provides robust electrical protection with its 1200A maximum current, electronic LSIG protection against overloads and short circuits, 60kA interrupting capacity, 1000V insulation voltage, and 8kV impulse voltage withstand, ensuring reliable performance and safety in demanding industrial applications with a mechanical and electrical life of 60 operations per hour.
Is Your Device Showing These Signs?
The Allen Bradley 140G-N6I3-E12-Z1 molded case circuit breaker commonly experiences issues such as nuisance tripping due to incorrect trip settings or thermal overload. We address mechanical failures including damaged operating mechanisms, broken handles, and faulty latching. Electrical problems such as contact erosion, open circuits, and short circuits within the breaker are diagnosed and repaired. Calibration drift affecting the accuracy of the overload and short circuit protection is corrected. We also resolve communication faults related to the breaker's electronic trip unit, ensuring proper Modbus communication and data transmission.
