Product Description
The Allen-Bradley 140G-J2C4-C25 molded case circuit breaker, manufactured by Rockwell Automation, is a robust, four-pole, size J frame breaker designed for reliable overcurrent protection in industrial three-phase systems. It handles rated currents of 25A and maximum currents of 250A, offers a 25kA interrupting capacity, and features fixed thermal and magnetic trips. With a 1000V insulation voltage and 8kV impulse withstand, this 7.72-pound breaker provides surge and fault protection, boasting a mechanical life of 240 operations/hour and an electrical life of 120 operations/hour for continuous operation.
Is Your Device Showing These Signs?
The Allen Bradley 140G-J2C4-C25 molded case circuit breaker commonly experiences issues related to thermal overloads, causing nuisance tripping due to incorrect current settings or ambient temperature fluctuations. Mechanical failures within the operating mechanism, such as a broken trip latch or damaged spring, prevent proper breaker operation and require component replacement. Electrical contact degradation, resulting from arcing or corrosion, increases resistance and generates excessive heat, leading to premature failure; inspect and clean contacts or replace the breaker. Furthermore, verify the integrity of the breaker's internal components using insulation resistance testing to identify potential short circuits or ground faults.
