Product Description
The Allen-Bradley/Rockwell Automation 140G-G2C3-D12 circuit breaker, rated at 120 Amps with a 25 kA interrupting capacity, safeguards circuits from overcurrent and short-circuit damage using dual heat-activated bimetal bars and a magnetic short-circuit sensor. It interrupts current flow via its three poles and can be reset after the fault is cleared. Designed for versatile mounting and resistance to harsh conditions (humidity, shock, vibration), it requires cables rated for at least 75C and operates within a 0-40C temperature range to ensure accurate heat detection. Installation and performance are enhanced by available internal and external accessories like flanged cables, motor operators, and auxiliary contacts.
Is Your Device Showing These Signs?
The Allen Bradley 140G-G2C3-D12 molded case circuit breaker commonly experiences issues such as nuisance tripping due to thermal overload or short circuit conditions, requiring inspection of connected loads and breaker calibration. Contact wear and degradation are frequent problems, leading to increased resistance and potential failure, necessitating contact replacement or breaker refurbishment. Handle mechanism malfunctions, including difficulty resetting or operating the breaker, demand handle assembly repair or replacement. Communication module failures within the breaker's electronic trip unit disrupt monitoring and control capabilities, warranting module replacement or firmware updates.
