What is the Martindale FD650?
The Martindale FD650 Digital Fuse Finder Kit is a complete fuse and circuit breaker identification tool designed for electricians and electrical testing professionals who need to locate fuses quickly and safely without interrupting the power supply. Featuring a digital receiver, plug-in transmitter and accessories for use on both socket outlets and light fittings, it provides fast, accurate results during fault finding, maintenance, and installation work.
How does the FD650 make testing faster for electricians?
The FD650 combines precision electronics with user-friendly design. The transmitter sends a coded signal through the circuit, which the digital receiver detects to identify the correct fuse or breaker instantly. Clear LED and audio indications make tracing simple, even in noisy environments. The included light fitting adapter and mains lead extend its versatility, making it ideal for electricians working across domestic, commercial, and industrial sites.
