Product Description
The Allen-Bradley 140G-H2H3-D12 is a robust, 125-amp molded case circuit breaker designed to protect electrical circuits with advanced Electronic LSI overload protection, a 25kA interrupting rating, and suitability for high-voltage environments up to 1000V, offering reliable performance and durability with a mechanical life of 240 operations per hour and an electrical life of 120 operations per hour.
Is Your Device Showing These Signs?
The Allen Bradley 140G-H2H3-D12 molded case circuit breaker commonly experiences issues such as nuisance tripping due to incorrect overload settings or thermal magnetic calibration drift. Failed shunt trips or undervoltage releases are frequently observed, preventing remote breaker operation. Contact erosion and mechanical wear within the operating mechanism lead to binding and failure to latch. Communication module failures disrupt network connectivity in networked breaker systems. Replacement of worn or damaged components, recalibration of trip units, and thorough testing resolve these problems.
