摘要:
An improved overcurrent automatic prevention apparatus having an individual fault display and permanent ground functions capable of automatically detecting whether overcurrent flows to a switch, which occurs due to a short of communication cables and properly limiting the overcurrent flow thereto, and when overcurrent exceeding a threshold value continuously flows thereto, permanently blocking a cable line and a ground side so as to prevent characteristic changes of a current limiting device and system breakage, and when it is possible to individually display fault states in order to easily check the system by providing an individual fault display device, visually checking a switch, and preventing possible faults in the system, thus increasing the efficiency of the operation, management and maintenance of the communication system, which includes a melting insulation material deposited on the upper surface of an input terminal of the semiconductor; a ground-side spring contact point disposed on the melting insulation material and connected to the ground; and a fault display lamp-side spring contact point disposed on the melting insulation material and connected to a fault display lamp receiving power.
