Rating of the best residual current circuit breakers for 2020

In the process of arranging a new apartment or private house, one should not forget about the main rules for installation and selection of 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 differential current switch.

Often, a properly sized differential circuit breaker can save a person's life. It is important to follow the basic installation rules.

Differential automaton - what is it?

Only high-quality RCBOs can guarantee full protection against short-circuit. They came to replace the usual many plug fuses, 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 automatic devices are gradually being replaced by RCDs, which guarantee not only protection against network surges, but also against possible leaks. The most popular devices can be purchased at your nearest hardware store or online store. However, the variety of products led to an unpleasant result, in connection with which most users began to buy the wrong model. It is impossible to determine with certainty which company is better to buy a difavtomat. Each design has both negative and positive aspects. The choice should be based on a combination of several factors, including:

• technical circumstances;
• Terms of Use;
• application area.

If necessary, you should get expert advice from a specialist, provided that it is not possible to independently answer the questions posed. Thus, you can purchase not only a high-quality, but also an optimal electronic-mechanical device at an affordable cost.

Design features and what it is for

According to many 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 difavtomats, but in vain. Modern electrical equipment consumes a huge amount of electricity compared to a few decades earlier. Based on such a huge indicator of energy saturation, it is necessary to protect your home as efficiently as possible from possible emergencies associated with electricity consumption.

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 be guided by the existing washing machine, pumps, electric ovens and a boiler, if it is not gas.

If equipment is planned that will be connected to each of the devices separately, one 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 automatic device, which contains the main protection functions and guarantees a comfortable use of devices in the future.

What is the reason for the popularity of models of Chinese difavtomats

It should be noted that almost all European-assembled products are distinguished by high quality and reliability indicators. The internal functionality has practically no differences. The main selection criteria for the modern buyer:

1. The ability to order products online. This decision is by no means related to a person's lack of desire to go shopping. On the manufacturer's website, you can purchase a quality product at an acceptable cost, which is indicated without any extra charges. And this is already a tangible benefit.
2. Terminals. They come in several types and, of course, it is better that the house has spare ones that will be needed for repairs. They can be purchased directly from the manufacturer.
3. Body shape. It may happen that the device is installed in a conspicuous place. In this case, the appearance of the adapter will play an important role.
4. The color palette of the top layer of the protective coating can also vary significantly from model to model.

The consumer can easily get lost among all kinds and numerous new products. Expert advice and personal preference will come to the rescue. Often, electricians advise the models they are used to working with. This suggests that, if necessary, they can be addressed in the future. In addition, European counterparts are often more expensive than Chinese counterparts by $ 25-50.

Rating of the best manufacturers

Hager

The German manufacturer produces products in a traditional silver case with a branded blue stripe. It should be noted that the location of the clamping terminals is very thoughtful. This will ultimately facilitate the subsequent installation. The contact status is visible on a special color indicator. It is located on the front panel, so it is easy to see through the cutout in the shield. They produce high-tech models of German quality.

• the body is made of durable material and is equipped with a wide button, which is convenient for both sealing and switching;
• clamping terminals are incredibly reliable and have a textured surface;
• perfect conductor connection even without ferrules.

• the location of the window with the inscription is extremely inconvenient (under the window itself, which makes it practically unreadable through the existing opening).

In the event that the device works, you need to open the door and see where exactly the leak occurred.

Legrand

The manufacturer is from France. A distinctive feature is not 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. The subsequent service will be as comfortable as possible.The large window is at the top, so it is clearly visible through the existing slot.

• contact strips - ribbed, which guarantees an excellent connection of wires;
• color indication - double (if a seal is installed, the unit will still indicate a leak by changing the color of the indicator);
• simple and intuitive panel, there is nothing superfluous on it that could distract the user's attention.

• not found.

It should be noted 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 exclusively engaged in the production of switches and sockets.

General Electric

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 dough is non-standard (located on the upper 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.

• the handles are made paired, thereby they open automatically to neutral and phase (a kind of insurance);
• the switch turns conveniently thanks to the wide handle;
• the manufacturer uses high-strength plastic, which is not afraid of significant mechanical and thermal stress.

• if other modules are located near the differential machine, then because of the handles it will be difficult to stretch the much-needed sealing cable;
• there is no identification window, so it is difficult to mark the line;
• the presence of a color indicator is not provided (with a fixed location, it will not be clear whether the device has worked or not).

Abb

German quality, which has a corresponding value. They are not engaged in the production of budget or low-cost models, due to which this brand tops the ratings of the most fake. A distinctive feature of the product is the presence of the “abb” chip on the left side with a convex plug. There is also a red line on the front side of the model, 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 of the same company. Without them, the connection of groups is not possible.

If there are only two difavtomats, the comb may not be needed when assembling the switchboard. But we are talking only about one-room apartments. In the presence of two or more living quarters and a shield for 5 diffs, the presence of a comb bus will greatly simplify installation.

• the location of the test is acceptable (directly above the plug), you can press on it without fear, because it is almost impossible to touch the handle;
• the presence of double color indication (even if the button is fixed, the protection will work and this will be evidenced by the corresponding indicator);
• the presence of paired buttons.

• the market is full of Chinese counterfeits (difficult to recognize);
• there is no identification window;
• on the right side, the screw terminals will be placed on the DS-951 series (installation can be difficult).

Schneider

It is such a product that is better to buy, based on numerous consumer reviews. The manufacturer has three main series:

A type	Short review
"Brownie"	The most affordable 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 product price. Buttons "test" and "inclusion" are located as conveniently as possible. They are black. 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. It copes with the assigned tasks and functions perfectly. It is better to buy such a differential even at the stage of building a new house.

• for the manufacture of the case, high-strength plastic is used, which is not afraid of temperature drops and mechanical stress;
• huge assortment;
• it is worth paying attention to the cost of products that are suitable for any budget.

• besides “brownie”, there is no color indicator in other series;
• identification window is not provided;
• contact clamps are located on one side, except for the "brownie".

It should be noted that the "brownie" (single-module difavtomats), the design is simplified. Compared to the products of a Russian or Spanish manufacturer, which use classical structural elements, they are characterized by a higher reliability.

It was necessary to significantly reduce the dimensions of the used type of release in order for it to fit into one module. This implies the installation of an additional amplifier and microcircuit that cannot function normally under high load conditions. Thus, the products will have a lower degree of reliability compared to similar devices with two modules.

Iek

A Russian manufacturer that produces not only electrical appliances. He has two series of diffs:

1. "AD-1". Outwardly, there are practically no differences. The only exceptions are paired switches, which simultaneously break the neutral and phase. There is a color indication above the switches. There are also separate holes for the comb, which will be very useful during the installation process.
2. "AVDT". A yellow switch is located on the body, and a color indication is located under it. The "test" button is small and gray, very convenient when pressed.

Both series use an electronic release. The choice of product will only depend on the mains voltage and the equipment used. It should be noted that they can also operate at low temperatures (down to -25 ° C). Electronic releases are cheaper than electromechanical counterparts. However, they are massively used when installing Chinese diffs.

• excellent service support (if necessary, equipment can be returned for repairs in any city);
• three-phase diffs are offered (only Chinese manufacturers put them on stream);
• installation of a three-phase model will cost significantly less than an automatic machine and an RCD;
• low cost compared to analogs of European assembly.

• identification window is not provided;
• the use of low quality plastic, due to which the case is fragile;
• the use of mainly electronic mechanisms (they are less reliable).

Install the best difavtomat or RCD separately

1. Based on the cost, it does not matter whether to buy an RCD or a machine. If the choice has settled on more affordable Chinese automation, then the final decision will be solely for the buyer.
2. The Chinese manufacturer is ready to offer both high-quality three-phase and single-phase diffs.
3. Installation of automation and RCDs will cost $ 50 or more. The advantage of the diff is that it has one less module (DIN-rail). However, from the point of view of economy, it is recommended to purchase a larger shield with a substantial margin.
4. In Europe, a separate device is often installed for each phase, so the demand for three-phase models is extremely low. Accordingly, the range of such products leaves much to be desired. Due to the fact that such devices are not in use, the cost of their production is much higher, and manufacturers prefer to make them exclusively to order.
5. If there is trust in one of the many brands, then the search for a suitable product will come exclusively from the available assortment.
6. There are no fundamental differences between single-phase models. An exception can be made by such a factor as dimensions. Their cost is approximately the same, so a person can spend a certain amount, both on the purchase of a machine and a set of RCDs.

What to look for when choosing a diff

Number of phases and indicator of rated voltage

This criterion is very convenient to carry out a selection of goods. The main thing is not to forget that in three-phase devices there are four poles, and in single-phase structures there are three terminals for connection. The manufacturer indicates the working pressure indicator in the technical passport and on the label. There is also a corresponding marking on the device itself so that over time the data is not lost.

Current rating

In order to guarantee the trouble-free operation of the differential, it is important to take this parameter into account. Such knowledge will help you choose a really high-quality device. This kind of information is indicated in the technical documentation of the product, its label and body, in the form of appropriate symbols. The figure represents the nominal value. For example, the designation "C30" indicates that the characteristic of the device is C, and the nominal voltage is 30 Amperes. This option is suitable for both multi-room apartments and small cottages. Their reliability indicator is significant, which is due to the high demand of buyers.

Leakage current. Maximum value

Most modern devices of this type are produced with the “30 mA” marking. On the case it is indicated in the form of a Greek symbol - delta. The number indicates the maximum current value. In order to choose the right unit with the appropriate parameters, you need to consult a specialist. He needs to be told about all connections and the electrical network used. If it is planned to use a group line, which will then be divided, then it will be sufficient to purchase a structure marked "30 mA".

This value is considered sufficient for most apartments. For a private house, it is better to buy a 300 mA model. Thus, the device will be characterized by a higher degree of safety and reliability. For an average apartment, this figure drops to "100 mA".

Once the decision has been made to purchase such a unit, the process of final product selection should be taken very seriously. It is necessary in every possible way to protect yourself from buying a fake, because only in this way you can get a high-quality and durable device at your disposal. To begin with, it will not be superfluous to familiarize yourself with the general characteristics of the models you like, and only then choose the most preferable option. It will not be deprived to get advice from a specialist if the buyer does not have the proper experience or knowledge from this industry.
