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.

Example of Acti9 circuit breaker bw for buildings and industry applications. Which one if for homes, which one for industry?
Applies to circuit-breakers, the main contacts of which are intended to be connected to circuits, the rated voltage of which does not exceed 1,V a.
I am from India. Document Status Indicators The Green document status indicator indicates that the document is: Difference is in the breaking technology and size.
Your eh or email address: Is there more in common? Dear Amey, If I understood your question well, the difference comes from ratio of nominal Icn and ultimate Icu breaking capacities ratio to service breaking capacity Ics.
MarvoSep 3, Also as i am new, how do i calculate my trip current? And I did engineering from electronics and communication in Reply i like this Reply I have never confused them yet maybe because its not much since I started working.
Dear Koks, Yes it is safe choice. Reply Hello Lim, It is higher because of lower Icu breaking capacity ratio to service breaking capacity Ics, eg.
BS EN – Low-voltage switchgear and controlgear. Circuit-breakers
Usually these circuit breakers sold by electrical retailers: They protect electrical power distribution of up to volts a. Posting a message to the forum will remove the above advertisement. Again there may be more recent versions of the document.
The same goes for impulse withstand voltage Uimp. I have started working in the industrial sector and am having trouble completing test certs for installations fed from panels.
BS or BS | Electricians Forum | Talk Electrician Forum | Electrician’s Talk
Whereas for industrial circuit-breakers, usual values of Uimp is 6 or 8kV, in line with the position of the circuit-breaker, at the origin of the installation. What this A or A meaning.
This is the reason why manufacturers in addition provide a wide scope of different curves: Consequences can be dire if residential CBs are used instead of industrial ones. And for prescribers to specify what CBs will be used for and then to check the standard for that use. For certain specific applications for example traction, rolling mills, marine service particular or additional requirements may be necessary. What is the right thing to say if they questioned us why we offered 6kAIC breaker?
Reply Dear Amey, If I understood your question well, the difference comes from ratio of nominal Icn and ultimate Icu breaking capacities ratio to service breaking capacity Ics.
No, create an account now. IEC covers all the types of the breakers: Click here to cancel reply. In order to use AC breaker in DC applications you should follow manufacturer recommendations.
Hello Yogesh, you can download them from IEC official website: Good luck for your job search! Like x 2 Informative x 2. Reply Thanks for your reply. HI I would like to know what have been the design and technological trend in low and medium 6947-2 and high current miniature circuit 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. Hello Jonas, No, your statement is not correct. If you need 15kA accordingplease check with local offer available, typically it is range of C Reply I have started working in the industrial sector and am having trouble completing test certs for installations fed from panels.
The Amber document status indicator indicates that some caution is needed when using this 6094-72 – 6094-72 is either:
