Allen-Bradley 140G-G3C3-C40 Molded Case Circuit Breaker

Allen-Bradley 140G-G3C3-C40 Molded Case Circuit Breaker is a 3-pole, G-frame protective device rated for 40 A, designed for industrial power distribution and motor feeders. As part of the 140G molded-case family from Rockwell Automation, it provides thermal-magnetic (T/M) overcurrent protection with a 35 kA interrupt rating, helping prevent damage from short circuits and overloads on three-phase circuits. The compact G-frame format supports rugged industrial environments and is intended for installation in control panels and distribution enclosures where reliable protection for 3-phase loads is required. With a rated current of 40 A, it accommodates common motor-start and feeder applications in light-to-moderate horsepower systems, delivering fast, predictable disconnection through its thermal-magnetic trip mechanism. The 140G-G3C3-C40 is configured for three-pole operation and is designed for straightforward line-side protection in industrial electrical architectures, enabling safe interruption of fault currents while preserving downstream equipment integrity.
