Allen-Bradley 140G-I3C3-D10 is a three-pole molded‑case circuit breaker (I‑frame) rated for 100 A and equipped with a 35 kA interrupt rating. It uses thermal-magnetic (T/M) protection to handle both overloads and short circuits, providing reliable three‑phase protection in industrial power distribution. Typical applications include feeders, motor circuits, and branch circuits in control panels, MCCs, and panelboards up to around 480 VAC. As part of the 140G family, this device is selected when a compact, rugged 3‑pole breaker with standard Allen‑Bradley integration is required.
