Műszaki információ: The fuse testing device can be used to identify faulty fuses quickly and easily. The fuse in the fuse socket or fuse holder is tested for correct function by applying the test contacts on the top side of the fuse casing without having to interrupt the power circuit. If the fuse is intact, the built-in LED lights up light green and will not light up at all if the fuse is faulty. Gripping pincers are available by turning over the test device, which can be used to remove fuses that need replacing right away. Of course, fuses can also be tested when they are disconnected. The fuse tester can be used to test standard (ATO), mini, MICRO2 and MICRO3 flat-type plug-in fuses.
