"A multipurpose way to find a fuse or circuit breaker without power sockets."

  • Description

    Martindale FD650 Elite Fuse Finder Kit

    The Martindale FD650 Elite Fuse Finder Kit brings microprocessor controlled multi-level sensitivity to fuse and breaker identification. A 6 segment bargraph gives progressive indication of signal strength which allows even faster identification.

    The Elite Fuse Finder can operate in two modes:

    • Automatic, which has a memory and the ability to automatically adjust sensitivity for foolproof identification.
    • Manual mode, which allows very rapid fuse finding using the 6 segment bargraph.

    This fuse finder kit is capable of operating with either the 13A plug top lead for sockets or the TL83 lead for light fittings or other points in a circuit where there are no standard 13A power sockets. Complete with a non-contact voltage indicator, the FD650 really is a multipurpose version of the F550.
