Product Description
The Allen-Bradley 140G-J2I4-C40, a Rockwell Automation molded-case circuit breaker, is a durable and reliable 40-amp device with a 250-amp current-carrying capacity, designed for industrial use and capable of handling up to 1000V insulation and 8kV impulse voltages; it offers electronic LSIG protection against overloads and short circuits, a 25kA interrupting rating, and a mechanical/electrical life of 240/120 operations per hour, all in a manageable 7.72-pound package.
Is Your Device Showing These Signs?
The Allen Bradley 140G-J2I4-C40 molded case circuit breaker commonly experiences issues such as nuisance tripping due to incorrect trip settings or thermal overload. Failed or damaged internal components, including the operating mechanism and solid-state trip unit, cause breaker malfunction. Contact erosion and contamination on the breaker's contacts increase resistance and generate heat, leading to premature failure. Inspect and address loose connections on the line and load side terminals to prevent arcing and potential damage. Verify proper coordination with upstream and downstream protective devices to ensure selective tripping and minimize system downtime.
