Product Description
The Allen-Bradley 140G-J6I4-D10 is a robust, high-performance, 250A molded case circuit breaker with a J-frame, 65kA interrupting rating, and advanced Electronic LSIG protection, designed for reliable and long-lasting protection in demanding industrial environments with up to 1000V insulation voltage and 8kV impulse voltage withstand.
Is Your Device Showing These Signs?
The Allen Bradley 140G-J6I4-D10 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 resulting in increased resistance and potential for arcing. Diagnose these problems by inspecting the breaker's trip unit settings, manually operating the reset mechanism to verify proper function, and performing a contact resistance test using a micro-ohmmeter to identify degradation. Replacement of the breaker is required if these issues persist.
