For some applications in the control cabinet or electrical switchgear, it is advantageous to protect the feed-through connection with a separate fuse. Fuse terminal blocks with fuse holder for DIN rail consist of a terminal block base and a fuse link carrier for various fuse links for AC and DC fuses.
The fuses vary from hinged fuse holders to plug-in fuse holders, screwable closures to flat plug-in fuses for cars and car mini fuses with and without LED status display. The fuse used limits the rated data (rated current and rated voltage) or the Low Leakage Current - LLC of the fuse terminal block.
