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.
Which is basically clean room heated 30 degrees domestic and office environments. 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. Like x 2 Informative x 2.
I was aware of the IEC standards of identical designations but didn’t know British Standards had adopted them. MarvoSep 3, Some breakers are suitable for use in both and environments but with a derated capacities.
And also a lot of manufacturers 6094-72 a cross over of standards when they produce devices so you really have to look at their documentation. StrimaSep 3, Yes Hagar and Eaton will make devices to both Standards so when filling out certs we should be stating MCBs are installed.
BS EN – Low-voltage switchgear and controlgear. Circuit-breakers
Still a lot of DBs with only s installed. You must log in or sign up to reply here.
