Product Description
The Allen-Bradley 140G-G6C3-C25 is a 25-Amp, 3-pole molded case circuit breaker from the 140G series, offering overload, ground fault, and short circuit protection. This G-frame breaker has a 65kA interrupting rating at 480VAC and provides fixed thermal (25A) and fixed magnetic (500A) protection with a non-interchangeable thermal-magnetic trip unit. It features a mechanical life of 25,000 operations (240/hour) and an electrical life of 8,000 operations at 415VAC (120/hour). Use 75C rated copper wire and operate within a 40C ambient temperature (storage: -40 to 80C). Dimensions are 76.2 x 70 x 130 mm, weight is approximately 1.1 kg. Disconnect power and protect from contaminants during installation/service. Replacement parts like end cap kits, insulators, and mounting hardware are available.
Is Your Device Showing These Signs?
The Allen Bradley 140G-G6C3-C25 molded case circuit breaker commonly experiences issues such as nuisance tripping due to thermal overload or short circuit conditions, requiring investigation of downstream electrical loads and potential recalibration of trip settings. Contact wear and degradation on the breaker's internal contacts lead to increased resistance, causing overheating and voltage drops, necessitating contact replacement or breaker refurbishment. Mechanical failures within the operating mechanism, including handle binding or inability to reset after a fault, demand inspection and repair or replacement of the breaker's internal components. Furthermore, ensure proper torque specifications are met during installation to prevent connection failures and subsequent arcing, which damages the breaker and connected equipment.
