Choose PeakTech 3432 - a reliable fuse locator
The PeakTech 3432 fuse tester is a clever tool that will identify the correct fuse in a few seconds, test the RCD, and check whether a wire is live. It works reliably both in the hands of a professional and a home DIY enthusiast who does not want to take risks when working with electricity. See how you can save time, nerves and… avoid an accidental short circuit.
Why is it worth having an electrical circuit locator in your toolbox?
Intuitive operation – you can handle it without instructions, even if it is your first time with
this type of equipment
Precise fuse location – you save time at every distribution board
Non-contact voltage detection (NCV) – you check wires without exposing yourself to
electric shock
Quick RCD test – you verify the operation of the residual current device with a single
button
Optical and audible signals – you do not have to look at the screen, the device will
inform you itself
Automatic switch-off after 3 minutes – you do not worry about battery consumption
Solid design with IP40 certification – you work in a workshop, basement, or on a construction site
without stress
Included in the set: receiver, transmitter, battery, and case – you have everything you need right away
after unpacking
3-year manufacturer's warranty – confidence in operation for a long time, even with intensive
use
Intuitive operation
Operating the PeakTech 3432 fuse tester is so intuitive that even beginners can handle it without difficulty. It is enough to see once how the transmitter and receiver work to understand the entire process.
One power button (which also serves as a reset function), clear LEDs, audible signals – it is impossible to confuse it. And if you want to know more, in the manual you will find clear connection diagrams and a description of the indicator operation. PeakTech 3432 works excellently with modern automatic circuit breakers, which are currently found in practically every home.
Safe voltage detection without touching wires
With the NCV (Non Contact Voltage) function, you do not have to take risks. After switching on the receiver, it is enough to bring the tip close to a cable or socket – if it detects voltage, it will notify you with sound and light. This is a great option when you want to make sure whether a wire is active before you do anything with it. A function especially useful in difficult conditions, e.g. in a junction box without access to wire ends.
Check the operation of the residual current device with one button
You do not have to buy a separate RCD tester. The PeakTech 3432 meter has this function built into the transmitter. Connect the device to a socket and press the button – if the RCD works correctly, it will trip immediately, and the indicator LED will clearly show it. This is an essential function during electrical installation inspections – both in homes and in commercial premises.
Well-thought-out design – convenience and durability in one
The PeakTech 3432 fuse locator is lightweight, handy, and fits well in the hand – you can use it comfortably even while working in tight distribution boxes or under sockets. The receiver housing is protected to IP40 class, which means resistance to dust and minor dirt – you can use it without worry in workshop conditions, a basement, or on a construction site.
The device design withstands drops from heights of up to 2 meters, which will be appreciated by anyone who works in difficult terrain or on a ladder. In addition, automatic switch-off after 3 minutes of inactivity helps save battery power, and the entire set fits easily into the included case – ready for transport, always at hand.
Everything you need is included in the set
In addition to the device itself, you receive a practical case, a 9V battery, and a complete manual. This is important because many competing models require purchasing accessories separately or starting the equipment with your own power source. Here you get a complete set – ready to work in the field, in a toolbox, or on a home shelf.
