Product Description
The Allen-Bradley 140G-J0C4-C63 is a robust 250 Amp, four-pole molded case circuit breaker in a J frame, designed for reliable multi-phase load protection with fixed thermal-magnetic trip, a 63A current range, a 100kA interrupting rating, 1000V insulation, 8kV impulse withstand, and a durable mechanical/electrical life of 240/120 operations per hour, weighing 7.72 pounds for easy control system integration.
Is Your Device Showing These Signs?
The Allen Bradley 140G-J0C4-C63 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 on the breaker's internal contacts lead to increased resistance and potential failure. The operating mechanism can become stiff or inoperable due to accumulated debris or corrosion, hindering proper breaker function. Furthermore, the breaker's enclosure may exhibit cracks or damage, compromising its insulation and safety ratings.
