Abstract: An LCDI device includes a shell, a movement unit, and a wire bundle assembly. The shell includes a base and an upper cover connected to each other. The movement unit is disposed in the base, and includes at least one connecting conductor. A first end of the wire bundle assembly is disposed in the upper cover and includes at least one shield detection line, where the shield detection line is electrically coupled to the connecting conductor. The shield detection line includes a connecting terminal at the first end of the wire bundle assembly which is configured to received and retain the connecting conductor inserted therein. The structure of the LCDI enables fast and secure assembling of the wire bundle assembly and movement unit, and eliminates the need for internal re-adjustment of the shield detection lines after assembling, which promotes automation of large scale production.

Abstract: A leakage current protection plug includes a body formed by a top cover and a base, a moving assembly disposed in the body, and output wires. The moving assembly includes a control circuit board, and a detector assembly and a trip assembly disposed on the control circuit board, wherein power input insertion plates and power output moving contact arms are assembled with the moving assembly. Each output moving contact arm is formed integrally and fixed to the detector assembly, and the output ends of the output moving contact arms are directly connected to the output conductor wires. The device has a simple overall structure and can be reliably assembled. By using integrally formed output moving contact arms to directly couple the input and output, it improves the accuracy of the leakage current detection parameters, reduces internal transfers and solder points, and reduces the size and cost of the plug.

Abstract: A ground fault circuit interrupter device includes a switch module having a reset switch, a control switch mechanically linked to the reset switch, a ground fault detection module, a self-testing module and a tripping module. The switch module controls the electrical connection between the input and output ends of the device. The ground fault detection module detects a leakage current signal at the output end. The self-testing module is coupled to the ground fault detection module and periodically generates a self-test pulse signal which simulates the leakage current signal. The tripping module is electrically coupled to the ground fault detection module and mechanically coupled to the switch module and the control switch, to control the movement of the switch module and the control switch. The control switch, which opens and closes at the same time as the reset switch, controls the power supply to the self-testing module.

Abstract: This invention provides a fireproof separator board, which is made of a flame-retardant, high temperature resistant material and disposed within an insulating casing of an electrical device, for preventing the heat generated by the electrical components of the electrical device from being conducted to the insulating casing. This invention also provides a plug-based circuit interrupter that includes the fireproof separator board. The fireproof separator board and the plug-based circuit interrupter of this invention can effectively prevent high temperature and fire caused by the electrical components that could melt the casing.

Abstract: An arc fault circuit interrupter includes: an insulating casing, electrical input terminals and electrical output terminals, first and second electrical path connected between the electrical input terminals and electrical output terminals, and a movement mechanism. The movement mechanism includes: first and second moving contact arms, electrically coupled to the first and second electrical paths, respectively; a control circuit board; an arc detection mechanism, electrically coupled to the control circuit board, for detecting an arc signal and causing the control circuit board to generate a trip signal; a tripping mechanism, electrically coupled to the control circuit board, for receiving the trip signal to disconnect the electrical coupling between the first moving contact arm and the first electrical path and/or the electrical coupling between the second moving contact arm and the second electrical path. The device can immediately cut off the power when detecting an arc signal to prevent fire hazard.
