This usually applies to fuses. In fact, what’s wrong with that - the “plate”, which melts and breaks the circuit at high current. Let’s buy any horrible (or maybe some more expensive) - and put …
In no case! Although the cost of a piece fuse is 5-10 rubles by force, but if you think about how many troubles a poor-quality “baby” can do, it becomes a little uneasy. There can be two such troubles for the owner of a car. The first - the fuse blows out of time, leaving the car at one “fine” moment, say, without the headlights. Bad, of course, but not so scary. But the second is much more dangerous! It is essentially the opposite: the fuse may simply not work during a short circuit! The result is burnt wiring or even the car itself.
In the next examination, we decided to test the flag fuses of a reduced size - these have recently been increasingly used on foreign cars - Mitsubishi, Honda, but you never know … They look like ordinary flag, but only a little red such…
They decided to buy not by piece, but by sets. Why? Well, firstly, there is at least some marking on the packages - sometimes the manufacturer is indicated (even if it’s “disguised”). Secondly, spare fuses of various ratings will not hinder the car owner - to check, so to check. Well, and thirdly, experience suggests that fuses sold individually, in fact, turn out to be the most, sorry, crappy … As a result, in Moscow stores we acquired five different sets of “kids”. The range of prices turned out to be very significant: the most expensive set is three times more expensive than the cheapest. And although you don’t particularly scare a car owner’s expense with a hundred rubles, we’ll see if the price is proportional to quality.
SEARCHING FOR A LEADER
What must fuses do? To work properly, that is, to blow out on time (not earlier and not later) and not try to turn into an ordinary resistor (the voltage drop across the fuse should be minimal).
To obtain reliable results, all the kits we bought were delivered for examination to the testing center of automotive electronics and electrical equipment "ETALON".
Comments for each of the sets are shown near the photo. The fuses that remained after the examination were also captured, they can be "admired" a little lower.
As a result, we found a clear favorite - an inexpensive and “conscientious” set of AVAR fuses in the Pskov plant. And once again they were convinced that nothing good should be expected from cheap products without marking and identification marks. But we buy them most often! Optimists, in a word …

A working fuse must:
- Do not burn out for 100 hours at a current 1.1 times higher than the nominal value (flashing of the housing is also not allowed);
