Allen-Bradley 140G-G2C3-D10 G Frame Circuit Breaker

Allen-Bradley 140G-G2C3-D10 is a three-pole molded-case circuit breaker from the 140G G-frame family, rated for 100 A and designed to protect three‑phase electrical distributions. It uses a thermal‑magnetic (T/M) trip mechanism to respond to overloads and short circuits, delivering reliable fault protection in panels and switchgear. The device carries a 25 kA interrupt rating, enabling quick clearing of faults and helping limit damage in typical industrial and commercial power networks. As part of the G-frame lineup, it shares the robust form factor and standard mounting common to 140G devices, making it suitable for retrofit or new installations in systems designed for this family. The D10 configuration indicates the base model’s three‑pole, 100 A, thermal‑magnetic protection characteristics, suitable for protecting feeders, motors, and other three‑phase loads. Optional accessories are available to extend functionality, including shunt-trip options for remote tripping and auxiliary contact kits for signaling and control integration, allowing coordination with automation and protection schemes in more complex installations. For applications requiring compact, reliable overcurrent protection with defined interrupting capabilities in industrial environments, the 140G-G2C3-D10 provides a proven solution within the Allen‑Bradley 140G MCCB portfolio.
