Allen-Bradley 140G-G6C3-C25-MT Molded Case Circuit Breaker

The Allen-Bradley 140G-G6C3-C25-MT is a 3‑pole, G‑frame molded‑case circuit breaker built for distribution panels that demand compact, high‑fault‑current protection. It uses a thermal‑magnetic (T/M) trip unit to provide both long‑time and instantaneous protection and is rated at 25 A with a 65 kA interrupt rating (at 480 V). This unit features standard bus bar mounting with top feed, designed for use with Rockwell Automation's 140G family mounting adapters (MCS, top connected) for secure installation in compatible switchgear. The G‑frame designation identifies its mid‑sized MCCB footprint, while the 800 V rated insulation voltage supports protection across typical industrial low‑ to medium‑voltage circuits. Weight is about 2.42 lb (1.1 kg), and the device is configured as a 3‑pole breaker to protect 3‑phase systems. With these specifications, it suits panelboards, MCCs, and feeder applications where precise 25 A protection and reliable interrupting capability are required, and it integrates into existing 140G lineups without modification.
