12 best auto manufacturers circuit breakers

Review of the best according to the editors. About the selection criteria. The the material is subjective, is not advertising and is not serves as a guide to the purchase. Before purchase is needed consultation with a specialist.

The circuit breaker is installed after input electricity to the apartment or house. It may be general or separate, to protect the drawn lines in different rooms to consumer appliances. The automatic device on shutdown in two ways: with thermal overload and short short circuits. In the first case, from the passage of increased current inside the machine heats the plate, breaking the contact. it prevents wiring from melting the winding. In the second case, when two phases are closed, the electromagnetic unit responds instantly sliding towards the shutdown, which protects the cable from fire, and electrical equipment from damage.

Unlike fuse plugs, reusable and after fixing the problem, they can be turned on again to restoration of the electrical circuit. These devices are equipped with residential premises, hospitals, schools, workshops and workshops. To facilitate choice we prepared a rating of the best manufacturers of automatic circuit breakers based on customer reviews and specifications manufactured products.

How to choose a circuit breaker

Before considering the manufacturers rating, we recall the main circuit breaker selection criteria so that subsequent the data in the TOP were understandable. Circuit breakers choose, paying attention to:

  1. Maximum rated current. The indicator varies from 1 up to 6300 A, and depends on the cross-section of the wiring. For example, if in a house laid wires with a cross section of 1.5 mm2, then an automaton from 15 to 20 will do A. You can find out the wiring parameters from the data on the winding or by measuring diameter of the exposed core.
  2. Number of poles. Varies from 1 to 4. Allows feed several lines from one machine at once. It saves place in the shield and speeds up the connection, but when one of the all directions are de-energized immediately. It also affects the connection to single-phase or three-phase network. Practical for the last option choose modular designs with three or four poles to completely disconnect the circuit with one device.
  3. Estimated load. This parameter is closely related to wire cross section, but also depends on the power of the connected devices to the line (electric kettle, electric stove, microwave, slow cooker and etc.). For example, if the total load on the machine is 5 kW, you need an indicator of 25 A.
  4. Response characteristic. This is the response time to increase in passing power. In an apartment where there are no high launchers currents, it is worth buying circuit breakers with a value of B, implying an instant response. In a private house having powerful electric boiler, characteristic C, suitable for passing primary increased current, and reacting only if it does not drop in the first seconds. For the workshop with machine tools choose electrical goods with category D.

The first place in the ranking of domestic manufacturers is Contactor factory. First, the company produced classic models circuit breakers, but then retrained and became focus on industrial series. Company produces switching devices for mounting on tires in the shield, as well as in separate buildings designed for individual place and closure shrouded. The household series is designated “Kpro” and supports current up to 100 A, all other machines exclusively industrial.

As our experts installed circuit breakers of this manufacturers have no analogues in the rating for maximum power protective devices. In addition to the “youngest” VAZ series, calculated for currents up to 250 A, Proton installations are able to interact with voltage up to 1600 A, and the line “Electron” up to 6300 A.

  • inlet openings are intended for cables with a section no more 25 mm2.

IEK

Rating: 4.5

IEK.jpg

This manufacturer is ranked with a registered office in Russia, but the production of electrical goods was established in China to reduce the cost of the process. The catalog of the company totals about 4000 positions, among which 200 types of circuit breakers. Brand every year tries to develop new models, for which he acts own laboratory, and tests, for solidity, are ordered in independent European centers. Among modular automatic machines produce models with 18 options of rated current from 0.5 to 64 A and characteristics B, C and D.

We added the manufacturer to the rating because it makes the best products for the price, and he has automatic devices not of the lowest quality. For example, models have deep set contacts, narrow case made of thick plastic and active indicator window with two colors (red and green). Wherein they cost half the price of imported ones, which is liked by absolutely everyone users in the reviews.

Advantages

  • simple connection with a curly screwdriver;

Chint

Rating: 4.6

CHINT.png

Chint’s products are “pure China” not trying disguise as other countries. But the manufacturer is releasing products at the factory and provides a wide selection of automatic circuit breakers, which would have been impossible with “artisanal” production. Modular devices are divided into the NB1, DZ47, DZ158, NBH8 series. TO The NB1 line is also available with accessories. All devices rated for alternating current up to 400 V. Automatic machines are executed in a narrow IP20 enclosure.

Our experts rated and added the manufacturer to the rating as producing the cheapest electrical products. All masters and ordinary users in the reviews agree that this is the most affordable option. At the same time, Chint is “industrial China”, and not self-made products, and the goods are accompanied by certificates quality.
