General Electric TF225D U Thermal Magnetic Circuit Breaker

General Electric TF225D U Thermal Magnetic Circuit Breaker is a protective device used in electrical distribution systems to interrupt fault currents and prevent damage to conductors and equipment; it is part of GE’s TF family and is designed for panel-board protection in commercial or light-industrial installations. It uses a dual-trip mechanism, combining immediate magnetic action for short circuits with a thermal element that responds to overloads, providing coordinated protection for feeders and downstream gear. This specific model is rated for 225 amperes and up to 600 volts, indicating the maximum continuous load and the voltage level it can interrupt. Typical applications include protection of feeders, motors, transformers, and other heavy-load circuits within commercial or light-industrial panels where a 225 A rating is required. Ensure device compatibility with your GE panel and the TF family mounting configuration when installing the TF225D U.
