In a circuit, the high heat generated by overload and short circuit can cause electrical fires. However, in the case of current R&D without overcurrent, a fault arc (arc or arc) caused by a small current also has enough energy to cause fire. Arc-Fault Circuit Interrupter (AFCI or AFDD) is the latest power protection device. GTAF series arc fault circuit breakers can effectively prevent electrical fires and human casualty accidents caused by short circuits, arcs, and residual currents (residual currents) caused by over-current, or line aging or poor contact in low-voltage distribution branch lines. The product. It can not only have traditional overcurrent (overload and short circuit), leakage protection, but also can detect fault arc in low voltage distribution lines and cut off the power in time to protect it.
