Product Description
The Allen-Bradley 140G-J0C4-C32 is a robust, high-performance molded case circuit breaker designed for reliable electrical protection in demanding applications, featuring a J-frame, 250A capacity, 100kA interrupting rating, fixed thermal/magnetic protection, four poles capable of handling 32A, 1000V insulation voltage, 8kV impulse withstand voltage, and a durable construction weighing 7.72 pounds, with a mechanical life of 240 operations/hour and an electrical life of 120 operations/hour.
Is Your Device Showing These Signs?
The Allen Bradley 140G-J0C4-C32 molded case circuit breaker commonly experiences issues such as nuisance tripping due to incorrect trip settings or thermal overload, failure to reset after a fault caused by a defective operating mechanism, and contact erosion or welding resulting in high resistance and compromised circuit protection. Field replacements are often necessary due to damaged or non-functional trip units, compromised insulation leading to dielectric breakdown, and mechanical damage to the enclosure or handle preventing proper operation. Routine inspection and preventative maintenance, including torque verification of connections and insulation resistance testing, mitigate these common failures.

Our Repair Process for the
140G-J0C4-C32
Our repair process for the Allen Bradley 140G-J0C4-C32 molded case circuit breaker begins with a thorough inspection to identify issues such as nuisance tripping, reset failures, contact erosion, or mechanical damage. We verify trip settings and examine the operating mechanism for defects. Contact resistance is measured, and insulation is tested to identify dielectric breakdown. Damaged or non-functional trip units are replaced, and compromised insulation is addressed. Mechanical repairs are performed on the enclosure and handle to ensure proper operation. All connections undergo torque verification, and insulation resistance testing is conducted as part of preventative maintenance. Field replacements are executed when necessary due to irreparable damage or non-functional components.
