Product Description
The Allen-Bradley 140U-I6C3-C35 is a compact, UL-listed, 3-pole molded case circuit breaker designed for industrial control panels. It offers superior short-circuit and thermal overcurrent protection for applications like control circuits, feeder circuits, HACR, and high-intensity discharge, boasting an interrupting rating up to 6 times higher than comparable breakers. Rated at 35 Amps for 230-690VAC circuits, it features a 65kA interrupting rating, 6000V impulse withstand, and 750V insulation voltage, with a mechanical lifespan of 100,000 operations. Its fixed thermal-magnetic trip unit uses a reverse loop contact and bimetal element for reliable protection. The breaker includes standard end cap terminals and mounting hardware for easy installation, and operates without de-rating up to 2000 meters altitude within a temperature range of -8 to 60 degrees Celsius.
Is Your Device Showing These Signs?
The Allen Bradley 140U-I6C3-C35 molded case circuit breaker commonly experiences issues related to nuisance tripping due to incorrect overload settings or thermal magnetic trip unit malfunction. Field failures often stem from contact erosion attributed to high fault current events or repetitive switching operations. Connectivity problems arise from loose terminal connections, requiring proper torque during installation. Calibration drift in the trip unit necessitates verification and potential adjustment to ensure accurate protection. Environmental factors, such as excessive heat or humidity, accelerate degradation and impact performance, demanding adherence to specified operating conditions.

Our Repair Process for the
140U-I6C3-C35
Our repair process for the Allen Bradley 140U-I6C3-C35 molded case circuit breaker begins with a thorough inspection to identify the root cause of the malfunction, focusing on nuisance tripping, contact erosion, connectivity issues, calibration drift, and environmental factors. Overload settings are verified and adjusted to the correct specifications, and the thermal magnetic trip unit is tested for proper functionality; if a malfunction is detected, the unit is recalibrated or replaced. Contacts are examined for erosion and are reconditioned or replaced as needed to ensure optimal performance. Terminal connections are tightened to the specified torque to eliminate connectivity problems. The breaker's operating environment is assessed to confirm it adheres to specified conditions, and recommendations are provided to mitigate future environmental degradation.
