How to choose a Circuit Breaker for induction hobs

Choosing a circuit breaker for an induction cooktop is not as simple as choosing one for the household. Below are some tips for selecting and installing a circuit breaker for induction cooktops. This is the best solution for safe cooking, convenient power disconnection for the induction cooktop, and especially for protecting the electrical circuit for your entire home.

You may have chosen circuit breakers for your home multiple times for various devices such as refrigerators, TVs, washing machines, etc. However, the way to choose a circuit breaker for an induction cooktop is completely different from that for household appliances. First of all, do you know what a circuit breaker is? What is its function? You may have heard a lot about this household electrical component but are not clear about its purpose.

Do you know how to choose the right circuit breaker for your induction cooktop?

In fact, a circuit breaker is an automatic switching device for household and industrial electrical appliances, such as single-phase, two-phase, and three-phase circuits. It is also known as a low-voltage circuit breaker, and in English, it is called a Circuit Breaker (abbreviated as CB). It can automatically cut off power when there are electrical issues such as overload, voltage drop, reverse power transmission, or short circuits, etc.

Choosing a circuit breaker for an induction cooktop is not simple at all, as there are many types, and not one type can be used for all induction cooktops. This is because circuit breakers have different technical specifications. To buy a suitable circuit breaker for the cooktop, you should have a formula for selecting the circuit breaker to both save investment costs and use it effectively.

Below is a very simple calculation method for selecting a circuit breaker and the best types of circuit breakers for induction cooktops that you need to note before going shopping.

20A Circuit Breaker:

Just like calculating the current in the house to choose a circuit breaker, the method for selecting a circuit breaker for an induction cooktop is the same. You need to check the total power consumption of the induction cooktop you are using. Typically, double induction cooktops (with 2 cooking zones) will have a power rating ranging from 1800W to 3600W. This power rating is suitable for electrical wiring of 2×2.5 – 2×3. Therefore, the smartest and most suitable choice for a circuit breaker for an induction cooktop is the 20A type.

30A Circuit Breaker:

If your induction cooktop has more cooking zones. Typically, families with many members or restaurants use double, triple, four, or even five-zone cooktops, which have a total power consumption quite high. From 3600W and above. You cannot choose a regular circuit breaker for the household but should choose a dedicated 30A circuit breaker for the cooktop to ensure stability and safety for the cooktop and household power supply.

Circuit Breakers from 30A – 60A:

High-end induction cooktops imported completely from abroad, such as European or Japanese cooktops, have a total cooking efficiency different from Vietnamese cooktops. Moreover, these products often have multiple cooking zones, with total power consumption that can exceed 7000W. At this point, you need to apply the formula for selecting a circuit breaker as well as the type of power supply cable suitable for the induction cooktop. The recommended type of cable for induction cooktops is a large current carrying cable with a power range of 2×4 to 2×10. For high-power induction cooktops, you should choose a circuit breaker of 30A – 60A.

Choosing a circuit breaker for the household is a smart decision to protect the entire electrical circuit system used in the house. Moreover, for those who are careful, choosing a circuit breaker for each individual electrical device such as refrigerators, washing machines, water heaters, induction cooktops, …

Which circuit breaker is good for induction cooktops?

The function of a circuit breaker is the ability to quickly switch the power supply, protecting the circuit when encountering issues. Currently, there are also types of circuit breakers that prevent electric shocks, ensuring safety during use, helping to prevent electrical short circuits and leaks that can cause fires if not extinguished in time. To ensure the induction cooktop operates stably, cooks safely, and protects your entire household electrical system, choosing and installing a circuit breaker for the induction cooktop is the best thing to do.

When you need to dismantle, repair, or install the induction cooktop with circuit breaker support, the household power supply system is still ensured, helping you save time and not affecting other electrical work in the house.

You will feel completely at ease when using an induction cooktop supported by an automatic circuit breaker that disconnects when there is a short circuit, electrical leakage, etc. Installing a circuit breaker is not too costly, so don’t overlook it if you are using an induction cooktop, infrared cooktop, or electric cooktop.

For families that rarely cook with induction cooktops or do not have them for a long time, installing a circuit breaker helps protect the cooktop as well as the electrical devices in the household best.

You should consider choosing and installing a circuit breaker for the induction cooktop, and not use circuit breakers indiscriminately. Because not all types of circuit breakers for induction cooktops are suitable. Refer to the method of choosing a circuit breaker, and absolutely do not use it indiscriminately. Not only will it not protect the induction cooktop, but it can also cause severe damage and ruin the entire electrical system as well as endanger your family’s safety.
