Polarity DC Breakers Explained

Confusion about how to correctly install Polarity DC Breakers, how they work, and why they are very dangerous if they are connected in reverse polarity.
Also, explain why regulation institutions want them out of the regulations and replace them with Non-Polarity DC breakers.

great video, i saw lots of videos on this topic on youtube but many of them were non technical persons and could not satisfy me, your video gave me 100% understanding, if possible please mention how to identify polarized and non polarized dc breaker physically

@@Iqbal_khan-9 awesome and glad it helped.

[@ltvtech]

@@Iqbal_khan-9 it would be best be shown on the diagram. Flow in one direction are Polarised breakers, also has magnet in, use small washer to feel if there is a magnet pulls or push. Normally Non-Polarity breakers will mention it clearly on it and show + / - on each pole

I went to your site for this paper and found much more great info Thanks much Logan, Tennessee, USA

Thank you Logan, glad it was helpful. South Africa is advancing quickly in renewable energy with our national grid failures. Chinese companies have so many specialists in DC Products, we used to get products from European countries, but they themselves manufacture there and just OEM their brands. Its my passion to dig deep into solar energy and share my experience and quality products. If you have TikTok follow me there on @johanmoesh I dont put all videos on KZbin. Will in the future create more on KZbin

These polarized breakers are confusing and dangerous..

[@odoohub5010]

Why do polarized breakers even exist? Is there any advantage of a polarized breaker over a non polarized breaker?

[@ltvtech]

They are cheaper, if used correctly they do the job, but it is very confusing for lots of people, installers etc. The problem will be human error, lots of it in South Africa,

Thanks for this video

What about those solar charger/inverters which provide current to the battery while charging and take out the current when load runs

[@ltvtech]

@@user-iw1dd9ql6f non Polarity breakers has to be used on them.

[@odoohub5010]

What about those breakers with indications as "line" on the top and "load" on the bottom. Are they also polarized breakers?

[@ltvtech]

It is very difficult to say on most brands, but use a washer, if it has magnet inside it is polarity breaker. Search and seek manufacturers specs. I want to say if they don't have + and - marking on the terminal screws it mostly would be Non-Polarity MCB

[@odoohub5010]

Are all mccb's non polarized?

[@ltvtech]

All, don't think so, but make sure from manufacturers, don't trust distributors. Most don't even know the difference
