Greetings.
I am researching requirements for switchgear in Europe and there are two prevailing series of standards: 60947-x and 61439-x. These series of standards are both produced by TC 121/SC 121A and there seems to have more than significant overlap in their scopes.. It does appear that 60947-x are for individual devices, while 61439-x appears to be for assemblages of devices, perhaps any number of 60947-x devices. I'm not certain I have that right. I have seen products the identify compliance with 60947-x and don't mention 61439-x. Neither standard series is mentioned in the list of harmonized standards for the LVD and are not excluded in Annex II. The application is for less than 1 kVac. Some 60947-5-x are mentioned in the Mach Dir., but 61439-x are not. (For the end-product application, the MD does not apply, though low voltage switchgear is in scope of the MD.) Interestingly, several 60947-x and 61439-x are mentioned in the list of harmonized standards for the EMCD. I note that the CENELEC web site identifies these standards as intended for use to demonstrate conformity with the essential requirements of the: * LVD * EMCD * RED and of these three, only the EMCD mentions any 60947-x or 61439-x standard. CENELC doesn't mention the MD at all, except for 60947-5-3 and 60947-5-5, which is at least consistent with the lists of harmonized standards for the MD. How does one choose the correct standard(s) between the two series? I am aware of 61439-0, but haven't yet purchased that document to discover what guidance it can give.
