IP55 or IP65 (or better) rated TPN board

pc1966 · Jun 10, 2023

We might need to have a small 3-phase DB in an industrial location that might be exposed to the elements occasionally, though normally it will be covered if rain, etc, is happening. Total current is no more than 32A but I am struggling to find any sort of conventional TPN board that is rated for this sort of thing. Currently I am pondering on making my own using these:

13960 | Schneider Electric Kaedra Distribution Board, 12 Way, 63 A | RS

uk.rs-online.com

A9XPH312 | Schneider Electric Acti 9 Busbar, 415V ac, 18mm Pitch | RS

uk.rs-online.com

And matching Acti 9 MCB/RCBO but I wondered if anyone on here has a better suggestion?

Thanks. Do you know the part number? A quick search found this but it is due to be discontinued:

SEA9BPN6HDGR - Heavy duty distribution board, Acti9 Isobar P B, 125A, 6 ways, steel door IP55 | Schneider Electric UK

SEA9BPN6HDGR - Heavy duty distribution board, Acti9 Isobar P B, 125A, 6 ways, steel door IP55

That's the one I was thinking of, hadn't realised it was being discontinued.

Normally I'd just go with a standard DB in a high IP rated cabinet anyway.

That is looking more likely.

I got a quote from Blakely and the 4 way TPN is £716 so on the pricey side, though looks pretty robust and Schneider innards are a good start.

Yes, Blakely build a lot of that type of unit for outdoor temporary use and also build a lot of stuff for London underground so do have a good name in this field.

Cannot you just put a standard board into a GRP inclosure? I’ve done that a few times.

You can also buy just the backplates, done that too for power distribution in a very large control panel, looked a very neat job.
