The best difavtomats for 2020

When a person equips a house or apartment, it is important to remember about the correct selection and installation of electrical networks. Therefore, the installation of 2 methods of protection is provided: against short circuit (short circuit) and against accidental contact. The first will prevent the occurrence of unforeseen circumstances, and the second will save a person's life. To protect against these influences, it is enough to connect a differential circuit breaker.

But connection is one process, because before this event it is important to choose the right device. Therefore, the editors of the site "bestx.htgetrid.com/en/" have prepared for you a rating of the best differential machines for 2020.

What can be replaced?

High-quality electrical circuit breakers (AB) can guarantee full protection against short circuits; this equipment has long supplanted outdated plug fuses, which were not particularly effective.

Residual current devices (RCDs) also play an important role in this system, and recently they have become mandatory, as they have all the positive characteristics that provide better safety.

Over the past few years, RCDs have been pushing back differential circuit breakers, which guarantee the owner reliable protection against short-circuit and leakage. In addition, the device can be bought at an affordable price in any building hypermarket. But this availability has led to the fact that some users, especially those who are not versed in electrical engineering, cannot find the right option. They often ask themselves what will be better and more reliable - residual current devices or difavtomat.

Unfortunately, it will not be possible to immediately answer this question, because both options have both a number of positive and negative sides. The exact choice depends on the application, conditions and technical circumstances. Therefore, each person should answer this question on their own or consult with a specialist who will help you choose the best option in a short time.

In what situation is the differential automaton better?

There are situations where a person only needs to install residual current devices. Even despite the main advantage of the difavtomat (it does not take up much space in the switchboard), it is best to refuse to buy it.

Modern man consumes many times more electricity than a decade ago, and if compared with the 20th century, this figure will outshine all records. Due to this energy saturation, the owner needs to provide himself with better protection so that the house becomes a fortress, and not fear.

It is recommended that the main attention be paid to the selection of equipment to ensure high-quality protection against current leakage. Therefore, it is important to carefully look for devices designed for a heating boiler (if it is not gas), an electric oven, a pump, washing equipment, etc.

When a person creates an electrical network diagram, it is important to remember the fact that the RCD, which is connected to each equipment, must also be protected against short-circuit, leaks and overloads. Therefore, not only these systems are selected, but a circuit breaker is also installed, and it is advisable to do this for each equipment. Because of this situation, you will need to buy a dimensional switchboard or just a differential automatic, which combines all the main protection functions and will allow you to use the electrical panel with maximum comfort.

What to look for when choosing?

As soon as a person has firmly decided to buy a difavtomat, it is important to pay special attention to the selection process. This way the user will protect himself from possible counterfeits and acquire reliable and durable equipment. First, it is important to look at the technical characteristics of each product, only then choose from those that are more suitable for a particular home.

Rated voltage and number of phases

It is easy to select a product by this criterion. It is enough to remember one nuance here: devices that operate in a single-phase network have 3 terminals for connection, in contrast to three-phase, where there are four of these poles.

The operating voltage is indicated on the label, in the technical passport, and is also marked on the unit itself so that the person does not forget about it.

Current rating

In order for the differential machine to guarantee trouble-free operation, it is important to look at such a parameter as the current rating. Knowing this criterion will help you choose a better option.

Information about this value is located on the label and in the accompanying documentation, indicated by a letter and a number, where the letter symbol denotes the characteristic of the product, and the number denotes the nominal value. For example, C30 indicates to the user that the machine is rated C while its rated voltage is 30 Amps. A suitable option for cottages and multi-room apartments are devices of characteristic C, they have good reliability indicators and are in great demand among buyers. It is best to look at a special table on the Internet when choosing this device.

Maximum leakage current

Most of the products are manufactured with a value up to 30 mA, similar information is placed on the case with the Greek symbol "delta", there is also a number that corresponds to the current value.

To choose the right product for this parameter, you should consult with a specialist and tell him about all electrical networks and connections.

If a group line is used, which is planned to be divided, then it is enough to buy a product where the characteristic will be 30 mA. This is the optimal value for most tasks. However, for input to a country house, it is recommended to install 300 mA models, as they guarantee reliability and safety. In apartments this value is less and is 100 mA.

A kind of RCD

Two classes of RCDs are built into the differential machine, each differs in the principle of operation and the method of safety:

• AND. Activated when DC leakage occurs. If you plan to connect to a network where various electronic equipment is used, then this is a suitable option that will make operation safe.
• AS... Prevents the entire system from operating as soon as an AC leak is detected on an electrical appliance or mains.

Additional security

A certain percentage of differential machines are equipped with special blocks that turn off household appliances when the neutral conductor breaks. If a person creates the safest conditions for the operation of electrical equipment, then it is best to buy this particular model.

Another important characteristic is the shutdown speed, everything is simple here, the lower it is, the better, however, it is important to understand that the maximum value is 0.3 seconds, it is not recommended to take products with a high rate, as it may not have time to respond to the problem.

If a person cannot understand or decide on the choice of a difavtomat, then it is best to contact an electrician you know or ask for help from consultants. If the latter option is chosen, then it is best to go to trusted stores that have a good reputation. The chance that there will be a big markup is minimal. Also, the buyer will have the opportunity to discuss each issue and find a suitable option in a short time.
