In the process of arranging a new apartment or a private house, one should not forget about the main rules for installing and choosing electrical networks. To avoid unpleasant situations in the future, several basic types of protection against contact and short circuit are used. One of them is a residual current switch.
Often, a properly selected differential circuit breaker can save a person's life. It is important to follow the basic installation rules.

Only high-quality RCBOs can guarantee full protection against short circuits. They came to replace the cork fuses familiar to many, which could not be called very effective. RCDs or residual current devices also play an important role in the development of this system, so over time they began to be classified as mandatory. In addition to numerous recommendations and advice from experienced electricians, they have a number of positive characteristics that guarantee a high safety rate.
In a highly competitive environment, differential automata are gradually being replaced by RCDs, which guarantee not only protection against surges in the network, but also against possible leaks. The most popular devices can be purchased at the nearest building supermarket or online store. However, the variety of products led to an unpleasant result, in connection with which most users began to buy the wrong models. It is impossible to determine with accuracy which company is better to buy a difavtomat.Each design has both negative and positive sides. The choice should be based on a combination of several factors, including:
If necessary, you should get experienced advice from a specialist, provided that it is not possible to independently answer the questions posed. Thus, it is possible to purchase not only a high-quality, but also an optimal electronic-mechanical device at an affordable cost.
According to numerous buyers, it is enough to purchase a cheap residual current device. It is due to the high cost that some people prefer not to buy difavtomatov, but in vain. Modern electrical equipment consumes huge amounts of electricity compared to a few decades ago. Based on such a huge indicator of energy saturation, it is necessary to protect your home as effectively as possible from possible emergencies associated with the consumption of electricity.
The main thing is to avoid mistakes when choosing protective equipment that could prevent the consequences of current leakage. When choosing a device, you should focus on the existing washing machine, pumps, electric ovens and a boiler, if it is not gas.
If you plan equipment that will be connected to each of the devices separately, you should not forget about protection against overloads and leaks. In addition to the general system, it will not be superfluous to acquire high-quality circuit breakers. If possible, they should be connected to each of the devices.To do this, you will also need a large-sized switchboard or differential machine, which contains the main protection functions and guarantees comfortable use of the devices in the future.
It should be noted that almost all European-assembled products are distinguished by high quality and reliability. The internal functionality is practically the same. The main selection criteria for the modern buyer:
The consumer can easily get lost among all sorts of types and numerous new products. Expert advice and personal preferences will come to the rescue. Often, electricians advise those models with which they are used to working. This suggests that, if necessary, they can be contacted in the future. In addition, European counterparts are often $25-50 more expensive than Chinese counterparts.
The German manufacturer produces products in a traditional silver case, with a branded blue stripe. It is worth noting that the location of the clamping terminals is very well thought out. Ultimately, this will facilitate subsequent installation. Contact status can be seen on a special color indicator. It is located on the front panel, so it is easy to see through the slot on the shield. They produce high-tech models of German quality.
In the event that the device works, you will need to open the door and see exactly where the leak occurred.
The manufacturer is from France. A distinctive feature is by no means the principle of operation, but the height of the case. This ensures excellent heat dissipation. The indicator window and buttons are located on a flat platform and at an acceptable distance from each other. Subsequent service will be as comfortable as possible. A large window is located at the top, so it is clearly visible through the existing slot.
It is worth noting that the company entered the market relatively recently, but has already managed to gain a strong position in the modern market. Previously, the brand was engaged in the production of exclusively switches and sockets.
The American concern produces not only electrical appliances, but also many other goods, including locomotives. The shape of the case is classic, however, the shape of the test is non-standard (located at the top left). The electromagnetic release is extremely reliable and incredibly resistant to overheating. Before choosing a device, you should consider this aspect. Subsequent repairs will not require special costs.
Electronic devices contain microcircuits that do not tolerate high temperatures. Due to this, they are cheaper than more technologically advanced and expensive models.
German quality, which has a corresponding cost. They do not produce budget or inexpensive models, due to which this brand tops the ratings of the most counterfeited.A distinctive feature of the product is the presence of the “abb” chip on the left side with a convex plug. Also on the front side of the model there is a red line, and the shape of the case is very specific. The installation process can be significantly complicated in the absence of auxiliary comb busbars and jumpers from the same company. Without them, the connection of groups is not possible.
If there are only two difavtomatov, when assembling the switchboard, the comb may not be needed. But we are talking only about one-room apartments. In the presence of two or more living quarters and a shield for 5 differentials, the presence of a comb bus will greatly simplify installation.
It is such a product that is better to buy, based on numerous consumer reviews. The manufacturer has three main series:
Type of | Short review |
---|---|
"Brownie" | The most cost effective models. Produced exclusively for the CIS by Bulgaria. A characteristic feature is the presence of a large orange button. The color indication is to the left of it. Clamp-type terminals are located on one side. |
"Easy-9" | Average price for items. The "test" and "on" buttons are located as conveniently as possible. They have a black color.The color indicator is not provided in the models, which is extremely inconvenient in subsequent use after sealing. It will not be possible to find out if the system has worked without removing the seal. In other series, they are located on the sides, which is very convenient for installation. |
"Acti-9" | A yellow latch and hemispherical buttons are a distinctive feature of the series. This is the manufacturer's highest quality product. He copes with the assigned tasks and functions perfectly. It is such a differential that is better to buy at the stage of building a new house. |
It is worth noting that the “brownies” (single-module difavtomatov) have a simplified design. Compared to the products of a Russian or Spanish manufacturer, which use classic structural elements, they are characterized by a higher reliability index.
It was necessary to significantly reduce the dimensions of the type of release used in order to fit it into one module. This implies the installation of an additional amplifier and microcircuit, which cannot function normally under high loads. Thus, the products will be characterized by a lower degree of reliability compared to similar devices with two modules.
A Russian manufacturer that produces not only electrical appliances.He has two series of differentials:
Both series use an electronic release. The choice of product will depend only on the voltage of the network and the equipment used. It should be noted that they can also work at low temperatures (down to -25°C). Electronic type releases are cheaper compared to electromechanical counterparts. However, they are massively used when installing Chinese differentials.
