Product Description
The Allen-Bradley 140G-M0H4-D80 is a robust, 800-Amp, four-pole molded case circuit breaker with an M frame, a 100kA interrupting capacity, and a sophisticated electronic LSI protection system, designed for reliable and safe operation in demanding industrial environments with a 1000V insulation voltage and 8kV impulse withstand voltage, offering a mechanical life of 120 operations per hour and an electrical life of 60 operations per hour, despite weighing 33.29 pounds.
Is Your Device Showing These Signs?
The Allen Bradley 140G-M0H4-D80 molded case circuit breaker commonly experiences issues such as nuisance tripping due to incorrect overload settings or thermal magnetic trip unit malfunctions. Field failures often stem from contact erosion caused by repetitive high fault current interruptions or improper torque on terminal connections leading to resistive heating and premature degradation. Calibration drift within the solid-state trip unit necessitates verification and potential adjustment to ensure accurate protection. Furthermore, inspect the breaker for mechanical binding or damage to the operating mechanism, which prevents proper opening and closing. Replacement of the entire breaker is required when internal components fail or the enclosure is compromised.

Our Repair Process for the
140G-M0H4-D80
Our repair process for the Allen Bradley 140G-M0H4-D80 molded case circuit breaker begins with a thorough inspection for mechanical damage, contact erosion, and terminal connection integrity. We verify the overload settings and calibrate the solid-state trip unit to factory specifications. The thermal magnetic trip unit undergoes testing to confirm proper functionality. If contact erosion or resistive heating is evident, we address the affected components. Mechanical binding or damage to the operating mechanism is rectified to ensure smooth operation. In cases of irreparable internal component failure or enclosure compromise, the entire breaker is replaced.
