Eaton Cutler-Hammer Fi3080L Universal Line Circuit Breaker

The Eaton Cutler-Hammer Fi3080L Universal Line Circuit Breaker is a 3-pole, 80-amp unit in the Fi family, designed for universal line protection in electrical distribution panels and power systems that require robust, multi-line overcurrent protection. The Fi3080L model provides simultaneous protection for three conductors by interrupting overcurrent events, helping prevent overheating, insulation damage, and potential equipment failure in demanding service environments. As part of the Fi series, this breaker offers a standardized, high-current protective option suitable for a range of installations where a single device must coordinate interruption across multiple lines. With an 80-amp rating and three-pole configuration, it supports feeders and higher-load branch circuits, delivering reliable protection to keep distribution systems safe and compliant.
