Which fuse is best? Expertise ZR

From penny candle, as the saying goes, Moscow was burned. The same fate when a simple malfunction can wait and the car if the battery is installed non-combustible fuses.

A valuable detail is burned first, saving the fuse.

From Murphy’s laws

In any case, a bad fuse can cause maximum harm? If you burn for no reason? Nothing of the sort — maximum damage will occur in case if the fuse refuses to burn out at a critical moment! And in advance to calculate the pest is almost impossible: it looks decent. And who would think that in a set of fuses from 5 to 30 And the manufacturer used the same fuse that can withstand the beyond current?

To detect these pests before installing on the car we purchased almost everything that caught the eye. Finally got up six naborchiki size and six Mini — size of the ATO. These fuses today mounted on most modern cars. The range of prices — from 40 to 100.

Even the mini-fuses is not necessary to check “on the knee” and equipped laboratories.Even the mini-fuses is not necessary to check “on the knee” and equipped laboratories.

What check?

From each set we selected for testing the most popular fuses — designed to current limit 10 and 20 A. According to ISO 8820-1:2014 to check products must meet two basic requirements.

First of all, the fuse should not interfere with the protected equipment to work properly — for this you need to drop the voltage on it does not go beyond the established framework. The physical meaning of this parameter is clear from the following example. If instead of the fuse enable circuit, for example, a powerful lamp, and it will properly perform protective functions, but protects the device do not have enough energy — all electricity will eat light. The mentioned setting is very important and all tested fuses its values were within tolerance.

These fuses imagines himself the light: cartridge is on red hot, but burn out is not willing.These fuses imagines himself the light: cartridge is on red hot, but burn out is not willing.

Secondly, the fuse should burn out if the current flowing through it exceeds the calculated. Check if current exceeding the value of 35%, immediately identified the main pests — they were sets Breckner and Bright Nova. These products are in all cases refused to burn out.

The specific results of each of the tested fuses is given in our photo gallery. Note that European products including Russian, has worked without any problems, while the Eastern part of the fuse went on strike. As usual, we specify that the results are specific to the sample and cannot be extended to all products of a particular manufacturer.

Some modern fuses has a built-in light indicator. In the initial state they shorted thermal fuse and if that blows, the glow immediately tells what the fuse needs to be replaced.Some modern fuses has a built-in light indicator.

The winner of the “SP Selection”, vote for the fuses of the Pskov JSC “AVAR”. The price is low, complaints about the quality there. Note that before the fuse of this enterprise did not fail in our examinations. It’s nice once again to maintain the integrity of the domestic manufacturer.

Good luck to everyone on the road! And let no fusible links did not spoil our mood!

АVАR, РоссияАVАR, Russia

When current is applied, exceeding the 35%, fuse 10 amp burned out after 3.4 seconds, dvadtsatiletnej — five seconds. The domestic manufacturer has confirmed his class. There are no comments.

Breckner, Kitajskih, China

Approximate price 50 RUB.

The fuse refused to burn out. Moreover, through 110 seconds after the start of the test housing 20-amp products hit the smoke and began to melt. Verdict: not good enough!

АVАR, РоссияАVАR, Russia

Approximate price 45 RUB.

Deationary burned in 6.8 seconds, dvadtsatiletnej — in 29 seconds. Claims to “pskovitianka” no.

Alca, ГерманияAlca, Germany

Approximate price 100 RUB.

The time the fuse blows, designed for 10 And 41 the second, 20-amp — 6 seconds. There are no comments.

Bright Nova, Nova КитайBright, China

Approximate price 65 RUB.

These fuses are not afraid of any current overload: fuse not want. Fuse glows like a dim bulb. In the car this is not the place.

MTA Italiamia, Italy

Approximate price 100 RUB.

Good products and say, in General, nothing. Deationary burned through 211 seconds, and a 20-ampere fuse in 26 seconds. Comments on “Italians” is not.

Breckner, Kitajskih, China

Approximate price 40 RUB.

Not burn! Glow, trying to melt the hull, but not burn out. The machine set is not recommended.

Bright Nova, Nova КитайBright, China

Approximate price 45 RUB.

Both products refused to burn out in the allotted time. During this 20-amp fuse in the end collapsed “atoms”, but never burned. Fail.

Nord Yada, Yada КитайNord, China

Approximate price 50 RUB.

Not all Eastern goods is a priori worthless. For example, the “Chinese people” know the business: one burned out after 2.8 seconds, the second — in 7.7 seconds. There are no comments.

Tesla, ЧехияTesla, Czech Republic

Approximate price 50 RUB.

The big name was of place. In the interval of 11.6 to 26.0 seconds burned two fuses, and rightly so. Claims to “Czechs” no.

King Company, Kitand Company, China

Approximate price 50 RUB.

Unfortunately, behave fuses refused all of ten minutes they quietly quietly passed a higher current. To the car to keep!

MTA Italiamia, Italy

Approximate price 120 RUB.

Both fuse worked in the range of 23-24 seconds after start of the test. Put the standings.
