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.

All in all there are so many interrupting ratings that I am so confused. I had these highlighted to me a few years ago and it was news to me. The best way to avert them is tightly worded, highly enforced national regulations. Again there may be more recent versions of the document. It applies whatever the rated currents, the method of construction ba the proposed applications of the circuit-breakers may be. The Red document status indicator indicates that the document is an old version The document has likely been withdrawn by the publisher, also the meta data presented here may be out of date as it is no longer being maintained by the editorial teams at NBS.
Example of Resi9 and Eazy9 circuit breakers for residential applications. I can say is that mix-ups of standards happen. Reply Leave a Reply Click here to cancel reply. The requirements for circuit-breakers not fulfilling the requirements for over-current protection are contained in Annex L. With additional requirements for integrally fused circuit-breakers. Thanks Reply Thank you for the useful infprmation.
BS EN Low-voltage switchgear and controlgear. Circuit-breakers
Stephen, the Max Zs value is not always published in technical guides. I would really appreciate any help provided. Applies to circuit-breakers, the main contacts b which are intended to be connected to circuits, the rated voltage of which does not exceed 1,V a. Which one if for homes, which one for industry? Reply Kevin, You should keep it simple: Dear Koks, Yes it is safe choice.
What will be be approximate short-time delay timing for A inrush? The Amber document status indicator indicates that some caution is needed when using this document – 600947-2 is either: They are both standards that specify requirements for low-voltage circuit breakers.
BS EN 60947-2:2017
Compare those numbers to the V upper limit between phases for residential MCBs. IEC covers all the types of the breakers: Also known as IEC The rating is the same in DC, there is a new magnetic threshold and voltage limitation. StrimaSep 3, Consequences can be dire if residential CBs are used instead of industrial ones. More details you can find in my blogs about standard https: This document Older versions. These are all written into the Standard so if you are installing MCBs in to areas of a Polution Level 3 then that circuit breaker is not fit for purpose.
Is there more in common? Em 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
Reply Thanks for your reply. For certain specific applications for example traction, rolling mills, marine service particular or additional requirements may be necessary. They protect electrical power distribution of up to volts a.
Icu is given only for range 5SY8. Reply Stephen, the Max Zs value is not always published in technical guides.
One more question regarding RCCB. Just those basic tech specs tell us how different the use of circuit breakers defined by our two standards are. Unfortunately I have no answer for the question. 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.
Pollution degree 2, impulse voltage 4kV, isolation voltage is the same as eb voltage V. In your given example its not exactly as you name 609477-2 Document Status Indicators The Green document status indicator indicates that the document is: I have started working in the industrial sector and am having trouble completing test certs for installations fed from panels.
Reply Thanks for useful information!!! Do you already 6947-2 an account? Supersedes BS EN These CBs are intended for use of indoor, pollution and humidity-free conditions: If such recommendations do not exist — its better to use dedicated DC offer.
