Product Description
The Allen-Bradley/Rockwell Automation 140U-I3C3-C80 is a Frame I molded-case circuit breaker designed for overload and short-circuit protection of equipment like motors and conduits. Operating between 220-690 VAC at 60 Hz, this 125 Amp, three-pole breaker uses a fast-acting fixed-thermal/fixed-magnetic detection system with bimetal bars and magnets. It requires installation in a protective enclosure, operates safely up to 40C without derating, and should be protected from corrosive substances. Wiring must be rated for 75C operation, and the drive's current rating depends on the applied voltage.
Is Your Device Showing These Signs?
The Allen Bradley 140U-I3C3-C80 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 are frequent problems, leading to increased resistance and potential failure to interrupt fault currents. We address mechanical failures in the operating mechanism, preventing proper breaker actuation and reset. Furthermore, we resolve communication faults within the breaker's internal monitoring system, ensuring accurate data transmission for power management and protection schemes. Replacement of damaged or degraded components, recalibration, and thorough testing restore the breaker to optimal performance.

Our Repair Process for the
140U-I3C3-C80
Our repair process for the Allen Bradley 140U-I3C3-C80 molded case circuit breaker begins with a comprehensive assessment to identify issues such as nuisance tripping, contact wear, mechanical failures, and communication faults. We address incorrect overload settings and thermal magnetic calibration drift through precise recalibration procedures. Contact wear and degradation are resolved by replacing affected components to reduce resistance and ensure proper fault current interruption. Mechanical failures in the operating mechanism are corrected to guarantee proper breaker actuation and reset functionality. Communication faults within the breaker's internal monitoring system are repaired to maintain accurate data transmission. The repair concludes with replacement of all damaged or degraded components, followed by rigorous testing to verify optimal performance and adherence to specifications.
