Product Description
The Allen-Bradley 140G-H3F3-D16 is a robust, 125-Amp H-frame molded case circuit breaker offering superior electrical protection with a 35kA interrupting rating and adjustable thermal-magnetic trip. Designed for high-voltage environments up to 1000V, it withstands 8kV impulses, handles a 160A current range, and provides reliable performance with a mechanical/electrical life of 240/120 operations per hour, all in a 2.65 lb package.
Is Your Device Showing These Signs?
The Allen Bradley 140G-H3F3-D16 molded case circuit breaker commonly experiences issues such as nuisance tripping due to incorrect overload settings or thermal magnetic calibration drift. Contact wear and degradation of the operating mechanism are frequent causes of failure, leading to breaker malfunction and inability to interrupt fault current. Field failures also stem from damaged or loose connections, requiring inspection and proper torque of terminals to ensure optimal performance and prevent arcing faults. Replacement of the entire breaker is often necessary when internal components degrade beyond repair, compromising its protective capabilities.
