    A missing or displaced indicator thus pinpoints a blown fuse. The removable part of the fuse holder has a small window to allow inspection of the indicator without removal of the fuse. The indicator button usually has a coloured dot indicating the fuse rating (see table). D- and D0-type fuses are used for protection of circuits up to 500 V AC ...

  3. Electrical fault - Wikipedia

    en.wikipedia.org/wiki/Electrical_fault

    Analysis of the prospective short-circuit current is required for selection of protective devices such as fuses and circuit breakers. If a circuit is to be properly protected, the fault current must be high enough to operate the protective device within as short a time as possible; also the protective device must be able to withstand the fault ...

  4. Fuse (electrical) - Wikipedia

    en.wikipedia.org/wiki/Fuse_(electrical)

    Normal fast-blow fuses are the most general purpose fuses. A time-delay fuse (also known as an anti-surge or slow-blow fuse) is designed to allow a current which is above the rated value of the fuse to flow for a short period of time without the fuse blowing. These types of fuse are used on equipment such as motors, which can draw larger than ...

  5. Fuse cutout - Wikipedia

    en.wikipedia.org/wiki/Fuse_cutout

    The fuse element, or "fuse link", is the replaceable portion of the assembly that melts and breaks the circuit when the electric current through it exceeds its rated current value. There are many types of fuse elements for many different uses such as a type T fuse also known as a "slow-blow fuse" being used for sidelines.

  6. Recloser - Wikipedia

    en.wikipedia.org/wiki/Recloser

    On a 3-phase circuit, a recloser is more beneficial than three separate fuse cutouts. For example, on a wye to delta conversion, when cutouts are used on the wye side and only 1 out of 3 of the cutout fuses open, some customers on the delta side have a low voltage condition, due to voltage transfer through the transformer windings. Low voltage ...

  7. Antifuse - Wikipedia

    en.wikipedia.org/wiki/Antifuse

    An antifuse is an electrical device that performs the opposite function to a fuse.Whereas a fuse starts with a low resistance and is designed to permanently break or open an electrically conductive path (typically when the current through the path exceeds a specified limit), an antifuse starts with a high resistance--an open circuit--and programming it converts it into a permanent electrically ...
