Memshield 2 availability/compatibility

[ccam108]

I'm looking for some breakers for our Memshield 2 DB (4x RCBO and 1x 3 Phase MCB) and it looks like the only place to get any is eBay, where I'm looking at about £40 each used!

Is there anywhere that still stocks Memshield 2 bits? Or is there any compatible drop in replacement? Do the Memshield 3 breakers fit?

Memshield 3 bits don't fit. I recently got a few RCBO's from my local Senate, but had to buy the breakers and the RCD modules separately (the RCD modules fit on top of the MCB's)

They aren't cheap though - around £50 each IIRC

Shame, because it's nice kit to work with.

have some in stock, but they're not cheap. The Memshield 3 uses a narrower busbar so depending on the board you could swap that out, and as far as I'm aware, that's the only size difference. I can check in the morning if you need

Didn't realise the RCD module just fitted onto the MCB. That will save a few pennies - the RCBOs were to replace existing MCBs

Iggifer - if you could check, that would be great thanks.

It is nominally impossible to remove the Memshield 2 RCBO pods from MCBs once they have snapped into place.

It can be done destructively, or by using tools and a technique.

AFAIK the pods can be fitted onto MCBs which have the red-green indicator beind a window, but not those without. The MCBs have a small plastic part above the switch protrusion that can be pried off. There are many variations of MCB so my description may not fit all.

John - The pods can be removed with ease? I have swapped several. Never had an issue.

You cannot fit the memshield 3 into the 2.

Agreed, I never had a problem with this either. They come with a longer tab to hold the whole module onto the rail, just remove that and the cover that goes round the test button and it should just slide off.

Memshield 2 mcbs are still available as well as the RCD pods.

Got a link? Would prefer to buy online.

Not online - I got some from my local independant wholesalers a few months back.

Memshield 2 in the middle, 3 on the outside and its bad news im afraid, quite a considerable height difference in the two. I hadn't realised. I tried to line up a piece of Eaton busbar and I wouldn't be happy with it like that. Depends what you've got in your board I guess though

That's very helpful thanks. I think we might actually have some Memshield 3s in the DB from the electricians idiots who "updated" our wiring, so it might be worth checking they are OK.

I've managed to source some second-hand RCD pods off eBay for £25 each which is a good start.

 

[Iggifer]

yea that's a pretty good price, assuming the mcbs are like the ones in the photos I posted, as the earlier ones don't accept rcbo pods
