Product Description

The Allen-Bradley 140G-KC6F3-D30 molded case circuit breaker, a 400A KC-frame device with a 65kA interrupting rating, provides reliable and adaptable circuit protection through adjustable thermal and magnetic settings. Rated for 300A, 1000V insulation, and 8kV impulse voltage, this 7.17 lb breaker offers a mechanical life of 120 operations/hour and an electrical life of 60 operations/hour, making it suitable for diverse applications requiring effective fault management.

Is Your Device Showing These Signs?

The Allen Bradley 140G-KC6F3-D30 Molded Case Circuit Breaker commonly experiences issues such as nuisance tripping due to thermal overload or short circuit conditions, requiring adjustments to trip settings or investigation of downstream electrical faults. Contact wear and degradation on the breaker's internal contacts lead to increased resistance, overheating, and eventual failure, necessitating contact inspection and potential breaker replacement. Mechanical failures within the operating mechanism prevent proper breaker operation, including difficulty in resetting after a trip or failure to trip under fault conditions, demanding a thorough mechanical inspection and repair. Calibration drift affects the accuracy of the breaker's protection characteristics, resulting in premature or delayed tripping, requiring recalibration or replacement to maintain proper circuit protection.
