The Allen-Bradley 140G-G2C3-C70 is a molded case circuit breaker from the G Frame series of the 140 product line, designed for versatile industrial applications requiring precise voltage and amperage compatibility. Featuring both thermal and magnetic trip capabilities, this breaker effectively safeguards against abnormal currents through its dual metal bars, with magnetic tripping specifically targeting short-circuit conditions. With an interrupting capacity of 25 kA, it serves as both a protective unit and feeder breaker, offering isolation, short-circuit protection, and thermal protection for feeder and branch wires in panels. However, its performance may vary under extreme temperatures or at altitudes over 2000 meters, as these conditions can affect its detection and interrupting functionality.
