    摘要： In one example, an arc fault circuit interrupter (AFCI) is provided. The AFCI may include a plurality of current arc signature detection blocks configured to output a plurality of corresponding current arc signatures, and a processor. The processor may be configured to receive each of the plurality of current arc signature from each of plurality of current arc signature detection blocks, respectively, and generate a first trigger signal. The processor may be further configured to assess each of the current arc signatures, determine whether an arc fault exists based on the assessment, and generate the first trigger signal if an arc fault is determined to exist. A method for detecting an arc fault is also provided.

    摘要： The present invention relates to a ground fault protection circuit and a ground fault circuit interrupter. A ground fault protection circuit may include a power supply circuit, a ground fault detection circuit, a signal amplifying and shaping circuit, a microcontroller control circuit, a power supply detection and indicator circuit, a tripping mechanism control circuit, and a reverse grounding detection and execution circuit. A ground fault circuit interrupter may comprise an interrupter body with a ground fault protection circuit in the interrupter body. The practice of the present disclosure may address installation safety risks of conventional ground fault circuit interrupters and arc fault circuit interrupter and improve the safety of ground fault circuit interrupters.

    摘要： A ground fault circuit interrupter includes a reset key, a reset mechanism, a conductive assembly configured to connect a power supply input side to a load side, a leakage signal detection circuit, and an electromagnetic tripping mechanism. The reset mechanism comprises a reset support and a support return mechanism. The reset support comprises a reset bracket and a support reset spring. The support return mechanism comprises a reset pole, a reset key spring, a compression spring, a reset block, a compression spring container, a reset slider, and a contact conductive part. The contact conductive part is disposed at a lower end of the reset slider and is configured to align with a position of a switch contact on a first PCB board. A state of contact or separation between the contact conductive part and the switch contact is configured to control an on-off state of the conductive assembly.
