12 best manufacturers of circuit breakers

Review of the best according to the editorial board. On the selection criteria. This material is subjective and does not constitute advertising and does not serve as a purchase guide. Before buying, you need to consult with a specialist.

The circuit breaker is installed after the electricity is supplied to the apartment or house. It can be common or separate, to protect the lines laid to different rooms to consumer devices. The automatic device operates to shutdown in two ways: with thermal overload and with short circuit. In the first case, the passage of the increased current inside the machine heats up the plate that opens the contact. This prevents the wiring from melting the winding. In the second case, when two phases are closed, the electromagnetic unit reacts, instantly shifting to the off-side, which protects the cable from fire, and the electrical equipment from damage.

Unlike fuse plugs, the machines are reusable and, after the problem is eliminated, they can be turned on again to restore the electrical circuit. Such devices are used to equip living quarters, hospitals, schools, workshops and workshops. To facilitate the choice, we have prepared a rating of the best manufacturers of circuit breakers, based on consumer feedback and the characteristics of the products.

How to choose a circuit breaker

Before considering the rating of manufacturers, we recall the main criteria for choosing circuit breakers so that the subsequent data in the TOP are understandable. Automatic circuit breakers for electrical circuit protection are chosen, paying attention to:

  1. Maximum rated current. The indicator varies from 1 to 6300 A, and depends on the section of the wiring. For example, if wires with a cross section of 1.5 mm2 are laid in the house, then an automatic machine from 15 to 20 A will do. You can find out the wiring parameters from the data on the winding or by measuring the diameter of the bare core.
  2. Number of poles. Varies from 1 to 4. Allows powering several lines at once from one machine. This saves space in the dashboard and speeds up the connection, but when one of the directions is triggered, all will be de-energized at once. It also affects the connection to a single-phase or three-phase network. For the latter, it is practical to choose modular designs with three or four poles to completely de-energize the circuit with one device.
  3. Estimated load. This parameter is closely related to the cross-section of the wire, but also depends on the power of the connected devices to the line (electric kettle, electric stove, microwave oven, multicooker, etc.). For example, if the total load on the machine is 5 kW, then an indicator of 25 A is needed.
  4. Response characteristic. This is the response time to an increase in transmitted power. In an apartment where there are no high starting currents, it is worth purchasing circuit breakers with a B value, implying instant response. In a private house with a powerful electric boiler, characteristic C is suitable, which passes the primary increased current, and reacts only if it does not decrease in the first seconds. For a workshop with machine tools, choose electrical goods with category D.

A domestic company called Delixi Electric, which produces circuit breakers under the DEKraft brand. A separate line was launched in Moscow in 2007 and is now known in Russia, the CIS and abroad. It is supplied to Europe under the second brand name Himel. Manufacturing facilities are located in China in three cities, which contributes to the production of high volume products and affordable cost.

We have ranked the manufacturer as the best in terms of price and durability. When the contacts are opened from a short circuit, the device will withstand 6000 cycles, but if the wiring is heated gradually from the increased load, then the device will be able to disconnect the circuit and recover after cooling the jumper up to 25000 times. Even European counterparts do not have this ability.


  • all factories comply with ISO9001 international certificates;
  • automatic circuit breakers are independently tested in international centers TUV (Germany);
  • for wholesale deliveries there are warehouses in Yekaterinburg and Moscow;
  • signatures on the state of the switch position in Russian.


  • due to the release under several brands, it is difficult to understand whose product it is;
  • current limitation 63 A;
  • inlet openings are designed for cables with a cross section of no more than 25 mm2.


Rating: 4.5


This manufacturer is in the rating with a legal address in Russia, but the production of electrical goods is established in China to reduce the cost of the process. The company's catalog contains about 4000 items, among which there are 200 types of circuit breakers. Every year the brand tries to develop new models, for which it operates its own laboratory, and tests, for solidity, are ordered at independent European centers. Among the modular machines, models are produced with 18 rated currents from 0.5 to 64 A and characteristics B, C and D.

The manufacturer was added by us to the rating, because it makes the best products for the price, and its automatic devices are not of the lowest quality. For example, models have deep-seated contacts, a narrow, thick plastic housing and an active display window with two colors (red and green). At the same time, they cost half the price of imported ones, which is liked by absolutely all users in the reviews.


  • simple connection with a curly screwdriver;
  • informative contact status window;
  • very affordable price;
  • accurate response to both systems (mechanical and electromagnetic).


  • marriage often comes across;
  • it is difficult to predict the service life;
  • with a short circuit in the wiring or electrical appliance inside, the machines burn out a little.

Best China Circuit Breaker Manufacturers

Rating: 4.8


This is a Chinese manufacturer in the rating, which is a direct competitor to the Russian IEK. It produces goods of similar price and of approximately the same quality. Since 2001, the manufacturer has been called 'Flavir', but in 2007 he re-branded the brand and expanded the range, entering the international level. Today the companies have 40 production sites and more than 3500 items of goods. According to the machines, there are one-, two- and three-pole devices designed for alternating currents of 240/400 V. The minimum value of the rated current starts from 6 A.

We marked the manufacturer in the rating due to the availability of switches with insulation withstands 690 V versus 660 V for competitors in the range. If there is a high voltage spike, they will better survive it. This affordable product also wins in terms of the number of electrical shutdown cycles: 10,000 versus 6,000.


  • automatic devices comply with GOST R 51327.1-2010;
  • there are modular and differential automata;
  • protect against overcurrents;
  • the manufacturer promises a warranty of up to 5 years.


  • small selection at par among small values;
  • may periodically turn off spontaneously;
  • sometimes difficult to start after shutdown (toggle switch returns to off position).


Rating: 4.6


Chint's products are 'pure China', not trying to disguise themselves as other countries. But the manufacturer produces products at the factory and provides a wide range of circuit breakers, which would be impossible with a 'handicraft' production. Modular devices are divided into NB1, DZ47, DZ158, NBH8 series. Additional accessories are available for the NB1 line. All devices are designed for alternating current up to 400 V. The machines are made in a narrow case with IP20 protection.

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 an 'industrial China', not a self-made product, and the goods are accompanied by quality certificates.


  • all kinds of response characteristics (B, C, D);
  • options for modular models with poles 1-4;
  • rated current with a step of 1 A in the range of 1-6 A;
  • the ability to install emergency contacts.


  • low wear resistance of the electromagnetic part – 4000 cycles;
  • operating temperature range from -20 to +40 (for others up to + 50º С);
  • for wires with a cross section of no more than 25 mm2;
  • awkward toggle lever (slippery and narrow).
