Simple tracing of fuses and breakers
Visual & audible indication
Fast manual mode
Self-adjusting auto mode
Mains powered plug-in transmitter
Dual function receiver & non-contact voltage indicator
The Elite 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. Plug in the transmitter to a live 13A mains socket and then scan the board with the digital receiver to quickly identify the right breaker with audible and LED bargraph indication.
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.
Each Martindale FD550 fuse finder is supplied with a receiver, transmitter, batteries and instruction manual.
