Induction Hob Comparison: 230V vs. 400V Supply Voltage - Usage, Performance, and Efficiency

Hello,

I need some help, I'm very green on this topic, that's why I started a topic in the beginner section, so please be understanding.

There are induction hobs with the parameter:

"230V supply voltage"

"Supply voltage 230V and 400V"

How do they differ in practice? for example, I bought a board that only has the 230V option, and the neighbor bought it with the 230V and 400V option, I had no option and connected to 230V, and the neighbor chose the 400V option, in which case it will be better? If the hob has only 230V, it will not be equal to a 400V connected hob in the sense that it will not be possible in some extreme situations, e.g. when 4 pots are set to full?

I know that when the board has two options 230 and 400, when it connects to 230, it cannot cope in extreme situations and then 400V is the better option, but if the board has only 230, the manufacturer probably predicted that there will be extreme situations and will pull on 230 all situations?

How does it show up?

Thanks in advance for the clarification

best regards

If I remember correctly, those on 230V have fields with a lower total heating power.

The main importance is the power of the plate, apart from a few facts, a 2kW / 230V hob will heat the same way as a 400V 2kW hob. However, taking into account the load capacity of the network, the 230V hob consumes more current, causing a greater voltage drop on the network, so it will heat a little worse. Additionally, it restricts the use of other devices.

But you figured it out, the installation is designed for current load and voltage drop. A 230V hob with the same power as a 400V hob requires an installation with a larger wire cross-section, not to mention a suitably stronger fuse. With a correctly selected electrical installation, it will not heat worse.

Of course you are 100% right but you probably did not read "ignoring a few facts". In most cases, the slab is selected for installation, and the installation under the slab is not modernized, although sometimes it is so. Anyway, the author of the post wrote that he had bought the album and not that he was going to renovate the kitchen.

I put forward a case where we have an installation under the board, let's say 5x2.5mm2 and we have a choice of a 230 and 400V board

Before buying, he should check what installation he has to know what to buy (board power) and whether it will be possible without replacing the installation.

Pole wise after the damage, the CD was bought and installed. But the topic is not about choosing the album, but explaining whether or not he made the right choice. Anyway, whatever you say here, everyone will do it as simply and cheaper as possible. I myself saw people stealing electricity from Chinese headphones, where it is difficult to say that it is copper, not to mention the cross-section.

It's not installed yet, I'm picking up the CD in two weeks but it's already paid and I have no choice.


I have the option of connecting to 230V because it is a regular contact and I can also connect to 400V, because there is the so-called PHASE in the apartment, the point is that at the last minute I changed my decision about the board and I did not notice that the new board cannot be connected to 400V and that's why I am asking if there is 230V on the disc, it will not be worse than another that I would connect to 400V, if there is no board for 400V, why should it be worse than 230V, the more that these boards, cheap for 1000 PLN, have all 400V and I bought it Bosch for 1900 PLN and I don't have 400V and that's why it makes me wonder

How powerful is the plate? If you have 400V in the kitchen, change the hob. What kind of pre-counter and post-counter protection do you have, do you have a separate protection for the board?

My board has 230V, such a board is enough for 230V or is it better for 400V? How do I know what my security is? I am completely green in the subject, so I am asking only about the basic difference and if 230V is enough for me

Warning

If you don't know anything, this album may not be suitable for your apartment at all. Assuming B16 on all sockets because you cannot have more, with the power of the 3.6kW plate you will have to turn off everything at home to be able to cook on 4 burners on full

If this is the album that you wrote about at https://www.elektroda.pl/rtvforum/topic3117667.html or PIT611F17E, it can be connected to both one and two phases. I don't know why you insist that this board is only 230V.

If the hob has, for example, 4kW, regardless of whether you connect to one phase or two, the hob will heat with the same power.

If you have a board, e.g. 9kW, connect to one phase and limit the settings (if possible) to the value safe for the installation, i.e. some 4kW, then you will have 4kW.

If you connect a hob with a power exceeding 4kW to one phase, you will most likely burn the installation / sockets / overcurrent protection will work.

Only a fortune teller can answer the question if a 230V hob is enough for you.

4kW cannot be connected to a 230V socket only to a "dedicated" circuit
