Telephone: +41 22 02 11 Telefax: +41 22 03 00 E-mail: [email protected] Web: INTERNATIONAL. STANDARD. IEC. Third edition. So how many are aware of the difference between these two Standards? I had these highlighted to me a few years ago and it was news to me. BS EN applies to circuit-breakers, the main contacts of which are intended to be connected to circuits, the rated voltage of which.

One more question regarding RCCB. Hello Jonas, No, your statement is not correct. I had these highlighted to me a few years ago and it was news to me. Also as i am new, how do i calculate my trip current? And for prescribers to specify what CBs enn be used for and then to check the standard for that use. By continuing to use this site, you are agreeing to our use of cookies. If you need 15kA accordingplease check with local offer available, typically it is range of C These are all written into the Standard so if you are installing MCBs in to areas of a Polution Level b then that circuit breaker is not fit for purpose.

All in all there are ba many interrupting ratings that I am so confused.

Reply Dear Max, you should verify the inrush current of the inductive load first. No, create an account now. Strima6094-72 3, But somewhere on the breaker it says Icu 20 KA. Good luck for your job search!

BS EN Low-voltage switchgear and controlgear. Circuit-breakers

What do they have in common? Still a lot of DBs with only s installed.

Procurement managers in utilities, too, can get things wrong. That is the reason why usually we meet limited number of printed technical information on CBs. Reply Hello Jonas, No, your statement is not correct. IECwhich I introduced at length in the first of these blog postsgoverns CBs for industrial applications. Some breakers are suitable for use in both and environments but with a derated capacities. Compare those numbers to the V upper limit between phases for residential MCBs.


Dear Koks, Yes it is safe choice.

BS EN 60947-2:2017

The requirements for circuit-breakers for equipment for example electrical appliances are contained in IEC The requirements for modular residual current devices without integral current breaking device are contained in Annex M. My thinking is that by nature AC signals reverse polarity each cycle and therefore it would not matter which way the MCB was wired.

Dear Max, you should verify the inrush current of the inductive load first. Which is basically clean room heated 30 degrees domestic and office environments. Kindly let me know if it is available on the Schneider site appreciate if Schneider can up load a youtube video Reply Dear Sumedha, Test procedures are explained in the mentioned standards. Understand that is making capacity and not Short Circuit capacity.

Their committees work with the manufacturing and service industries, government, businesses and consumers to facilitate the production of British, European and International standards.

IEC 60898-1 and IEC 60947-2: a tale of two standards

In any case it will break 15kA. They are both standards that specify requirements for low-voltage circuit breakers. Typically IEC certified CBs meet minimally required performance to proof proper protection of household installations: I would recommend to find the answer by contacting technical support team in the country. I was aware of the IEC standards of identical designations but didn’t know British Standards had adopted them.


BS EN – Low-voltage switchgear and controlgear. Circuit-breakers

The most suitable solution for use are MCBs certified with both standards as their performance meets requirements of use for residential installations and high enough for use in industry and infrastructure applications. Which one if for homes, which one for industry? Also known as IEC IEC covers all the 600947-2 of the breakers: Stil… 1 Can we say it is for industrial application if a MCB manufactured as per IEC only 2 According to these standards any manufacturers could provide life time warranty.

The requirements for circuit-breakers for the protection of wiring installations in buildings and similar applications, and designed for use by uninstructed persons, are contained in IEC Stephen, the Max Zs value is not always published in technical guides. Reply I am confused with two standards for the same breaker.

I have started working in the industrial sector and am having trouble completing test certs for installations fed from panels. Example of Acti9 circuit breaker used for buildings and industry applications.

Like x 2 Informative x 2. And also a lot of manufacturers have a cross over of standards when they produce devices so you really have to look at their documentation.

The rated voltage currently required in industrial-use CBs isvolts or higher. Yes Hagar and Eaton will make devices to both Standards so when filling out certs we should be stating MCBs are installed. Difference ba in the breaking technology and size. Thanks for your reply.
