Product Description
The Allen-Bradley/Rockwell Automation 140G-J2F3-D20 is a 200 Amp, 3-pole J-frame molded case circuit breaker (frame rated at 250 Amps) designed to protect control systems from short circuits and abnormal currents. It uses fixed thermal and magnetic trip mechanisms, offering a 25kA interrupting capacity. Unlike fuses, which require replacement after tripping, this circuit breaker can be reset for continued operation, making it a more cost-effective solution in many applications. Note that its thermal trip characteristics are temperature-dependent, potentially carrying more or less current than rated below or above 40 degrees Celsius, respectively. It is designed for enclosure mounting.
Is Your Device Showing These Signs?
The Allen Bradley 140G-J2F3-D20 molded case circuit breaker commonly experiences issues such as nuisance tripping due to incorrect overload settings or thermal magnetic trip unit malfunction. Contact wear and degradation are frequent problems, leading to increased resistance and potential failure to interrupt fault current. Calibration drift in the electronic trip unit affects protection accuracy, necessitating recalibration or replacement. Mechanical failures in the operating mechanism, including handle breakage or difficulty resetting, require repair or breaker replacement. Furthermore, corrosion on the bus connections and terminal lugs increases resistance, causing overheating and potential fire hazards; proper cleaning and tightening resolves this.

Our Repair Process for the
140G-J2F3-D20
Our repair process for the Allen Bradley 140G-J2F3-D20 molded case circuit breaker begins with a thorough inspection to identify issues such as nuisance tripping, contact wear, calibration drift, or mechanical failures. Overload settings are verified and adjusted as needed, and the thermal magnetic trip unit is tested for proper function; malfunctions necessitate unit replacement. Contact surfaces are cleaned and reconditioned to reduce resistance, and degraded contacts are replaced. The electronic trip unit undergoes recalibration to restore protection accuracy; units beyond calibration are replaced. Mechanical components, including the operating mechanism and handle, are repaired or replaced to ensure proper operation. Bus connections and terminal lugs are meticulously cleaned and tightened to eliminate corrosion and prevent overheating.
