Martindale Part No: MARFD650

The Elite Professional Fuse Finder makes identifying poorly labelled fuses and breakers easy without the need to power down each circuit to identify the one you need to work on.

The comprehensive professional Kit expands the capabilities of the standard FD550 so that it can also be used on light fittings or other points in a circuit in addition to 13A sockets.

The receiver has both fast manual mode and auto threshold mode set by a single sweep over the board. The auto mode sets the sensitivity to ignore weaker signals which can be caused by coupling between circuits ensuring easy detection in a wide range of installations.

The receiver will work with multiple transmitters and can also be used as a non-contact voltage indicator.

The kit includes a twin lead set with crocodile clips (TL83), IEC mains lead (EX332) and a soft carry case.
