  • MULTIFUNCTIONAL ELECTRICAL POWER OUTPUT PROTECTION DEVICE
    Publication number: 20150349514
    Abstract: A multifunctional electrical power output protection device includes a protection device having a circuit board. The circuit board is mounted in a receiving space of the protection device and includes an input port, an output port, a switching element, a detection element, and a manually-operating overriding device. The manually-operating overriding device is electrically connected to an end of the detection element. The switching element has an end electrically connected to the input port and an opposite end electrically connected to the output port. The detection element has an end electrically connected to the input port and an opposite end electrically connected to the output port. The switching element and the detection element that are connectable to an external power supply respectively provide an effect of preventing backward charging induced by a reverse electrical current and effects of over-loading interruption and current-limiting protection.
