Old Rewireable Wylex R5 (M12?) to Wylex MCB

[abusimbel]

Quick question and thanks in advance for your help.

I want to replace my old Wylex rewireable fuses with new plug-in MCBs. I've looked over the forum and think I need to replace them with these:
Wylex MCB - for Old NN Consumer Unit
Wylex - NB 05, NB 15, NB 30

I just want to make sure these are plug-in MCBs that will fit my old plug-in rewireables. None of the photos of these show the backs. I want to make sure the plugs are the same width apart. So does anyone know if these are plug-ins and are they the correct MCBs for the old R5, R15, R30 rewireables?

I am calling them R5s from the Wylex catalogue but mine have M12 stamped on the inside. Old product number perhaps?

I have attached photos.

Thanks very very much.

have you bought your MCBs yet? If not, change your profile to make your email address visble, and see what happens.

"NN" is not the correct type. yours is a Wylex Standard. IIRC when Wylex brought out their new ranges to replace the old Standard, they designated then with an "N" for "New Design"

If you have been looking at these, they won't fit.

You need these, or the previous model which had buttons

JohnD,

Thanks much. I haven't purchased the MCBs yet. I've made my email visible now. I was looking at the ones in the first photo. Any idea what the product name/number is for the ones you showed me that I do need?
Thanks again.

JohnD,

Nevermind it looks like I've found them on the TLC-direct website. They are N5,N10 etc. Thanks again for pointing me in the right direction.

Oops I meant B5,B10 etc...

Oops I meant B5,B10 etc...

Those desinations are the type and rating, not the range, mate

B10 = 10amp BSEN60898 type B
C32 = 32A BSEN60898 type C

and so one

But as I understand it the part number for Wylex's plug-in MCB's are:

B6
B10
B16
B20
B32
B40

Whereas the cartridge fuses are:

C5
C15
C20
C30
C35
C40
C45

And the 3036 fuses are:

R5
R15
R20
R30
