Product Description
The Allen-Bradley 140G-N0H4-E12 is a heavy-duty, four-pole molded case circuit breaker designed for high-current (1200A) industrial applications, offering electronic LSI protection, a 100kA interrupting rating, 1000V insulation, 8kV impulse withstand, and a robust N-frame construction for reliable overcurrent protection and safe disconnection in demanding environments, with a mechanical/electrical life of 60 operations per hour and a weight of 27.56 pounds.
Is Your Device Showing These Signs?
The Allen Bradley 140G-N0H4-E12 molded case circuit breaker commonly experiences issues related to nuisance tripping, often stemming from incorrect overload settings or thermal magnetic trip unit malfunctions. Field failures are attributed to contact erosion due to repetitive high fault current interruptions, requiring replacement. Connectivity problems arise from damaged or loose terminal connections, causing voltage drops and operational disruptions. Calibration drift in the electronic trip unit leads to inaccurate protection, necessitating recalibration or unit replacement. Environmental factors such as excessive humidity or temperature fluctuations accelerate component degradation, impacting overall breaker performance and lifespan.

Our Repair Process for the
140G-N0H4-E12
Our repair process for the Allen Bradley 140G-N0H4-E12 molded case circuit breaker begins with a thorough inspection to diagnose nuisance tripping, contact erosion, connectivity problems, calibration drift, and environmental damage. Overload settings are verified and adjusted as needed. The thermal magnetic trip unit is tested for malfunctions and replaced if necessary. Contact points are examined for erosion; breakers with significant erosion undergo complete replacement. Terminal connections are tightened or replaced to eliminate voltage drops. Electronic trip units exhibiting calibration drift are recalibrated; units beyond calibration specifications are replaced. Breakers showing signs of environmental degradation are assessed for component damage, and affected parts are replaced to ensure optimal performance and extend the breaker's lifespan.
