Product Description
The Allen-Bradley 140G-H15C4-C35 is a robust, 4-pole, 125A molded case circuit breaker with a 150kA interrupting rating, fixed thermal-magnetic protection, a 35A current range, 1000V insulation voltage, and 8kV impulse withstand voltage, designed for reliable, long-lasting protection of multi-phase electrical circuits in high-voltage environments, weighing 3.53 pounds and offering a mechanical/electrical lifespan of 240/120 operations per hour.
Is Your Device Showing These Signs?
The Allen Bradley 140G-H15C4-C35 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 on the line and load side connections are frequent problems, leading to increased resistance and potential thermal runaway. Furthermore, the operating mechanism can become stiff or fail, preventing proper breaker actuation and requiring inspection of the spring mechanism and lubrication of moving parts. Field reports also indicate occasional failures within the solid-state trip unit, necessitating functional testing and potential replacement to ensure accurate fault detection and protection.

Our Repair Process for the
140G-H15C4-C35
Our repair process for the Allen Bradley 140G-H15C4-C35 molded case circuit breaker begins with a comprehensive visual inspection for contact wear, connection degradation, and physical damage. We then perform rigorous testing of the solid-state trip unit to verify accurate fault detection and protection. The operating mechanism is thoroughly inspected for stiffness or failure, with the spring mechanism examined and moving parts lubricated as needed. Overload settings are verified and adjusted to eliminate nuisance tripping, and thermal magnetic calibration is performed to correct any drift. Finally, all line and load side connections are meticulously cleaned and tightened to minimize resistance and prevent thermal issues, ensuring the breaker functions according to its original specifications.
