Why are fuses needed for Opel Astra H?

Opel Astra H fuses are needed to open an electrical circuit that has been overloaded. Simply put, if the current in the circuit increases, the fuse blows, and the circuit opens accordingly. This is necessary to prevent a short circuit, which can lead to the breakdown of all electronics in the car, and even to a fire. The block was created for the convenience of the car owner. After all, if fuses were scattered throughout the circuit, it would be very difficult to replace them. Thanks to the fact that they are all collected in one place, you don’t have to search throughout the car to find the one you need.

How to identify a malfunction

The Opel Astra H boasts a fairly large number of electrical appliances. Therefore, if one or more of them fails, the first thing you need to do is check the fuses. It will not be difficult to identify a faulty one; in the center it will be blackened, possibly slightly melted, and the metal contact in the middle will be broken. Replacement does not require special fuses specifically for the Opel Astra; this part is universal and inexpensive. The main thing is not to make a mistake with the current strength. The number of amperes will be written on the part itself. In addition, the diagram in the Opel Astra H operating manual and color identification will help:

  • The purple part can withstand 3A,
  • beige - 5A;
  • brown - 7.5A;
  • red – 10A;
  • blue – 15A;
  • yellow – 20A;
  • transparent – ​​25A;
  • green – 30A;
  • pink – 40A.

Fuses blow out most often due to improper operation of the car. For example, when the windshield or headlight washer fluid freezes, the driver begins to repeatedly press the washer control paddle on the steering wheel. The liquid is not pumped, the electricity in the circuit increases, and accordingly the part burns out. The same result awaits the cigarette lighter if you insert several electrical appliances into it at once, or one that is too powerful. Also, the low beam headlight fuse often suffers because the wrong lamp is used.

The Opel Astra H is a popular model of budget sedans produced by the German concern in the period 2004-2009. This car has gained great popularity in almost all regions of the Russian Federation due to high-quality body assembly and a relatively reliable power unit.

However, for proper operation of the car, it is necessary to maintain the equipment in a timely manner, in particular, monitor the condition of the wiring and correctly change fuses.

Location and layout

The most popular location for fuses is in the interior or under the hood (they are located near the washer). Each car has its own layout, depending on the location (near the cigarette lighter or washer). The diagram is necessary in order to better understand the processes taking place, as well as the principle of operation. Some types of cars (for example, trucks) may have more than one fuse box, or even 4 or 5. They may also be scattered throughout the car, but this rarely happens.


Fuse box in the engine compartment

In the Opel Astra there is not one unit, but two. Their location is in the engine compartment and passenger compartment (near the cigarette lighter). A diagram of the operating processes in the Opel Astra and the elements protected by fuses is located just below.

What is it and why do we need it?

A fuse is a device that protects electricity consumers and electrical circuits from short circuits and system overloads. It contains an insulating body, fuse links, as well as a special terminal that connects the fuse links and the electrical circuit. To avoid overheating, some parts also contain quartz sand.

The fuse box is needed in order to protect the system and prevent fire in case of a sharp increase in current level. This happens due to the fact that they burn out first. Basically, such an element is disposable.
