I need to replace some circuit breakers in a very old DB.

Anyone know what adapters I can use to mount DIN circuit breakers onto this old system?

Any idea what this old system is called?

You have an example of the adapter on the right side, that is what you need to fit the new type of circuit breakers, 

I would rather chuck all that old Heinemans away and install a Din rail with new din circuit breakers.

That old breakers are from the early sixties and most probably that earth-leakage device does not function correctl anymore.

Vir Wat??.... Only joking! 

I agree, and whats more the cost of these devices, or even the mini rail ones are very high in relation to DIN.

I tried putting a Din circuit breaker there, but I couldn't get it to fit.

Will look again later.

Chucking away those old breakers (and EL) is exactly the plan. I'm just trying to figure out how to fit the new breakers.

You reckon I should just screw in a Din rail?

Yes, you could replace the old rail with the new type of Din rail, I replaced all my old Heinemann CB using that adapter and it worked well for me.

Rather measure the existing back plate and see if you can't get a new din rail back plate that will fit on the 4 studs, complete with new face plate.

where would I look for that?

Din rail is sold in length. So you can buy a short length and merely cut it to size. You can also drill easily new holes to align with mounting holes. 

You may have to add some standoffs to get the desired height you need for the faceplate.

After pricing main switches, earth leakages, DIN rails etc, it actually worked out cheaper to buy a pre-populated Veti DB which I'll fit into the cavity in the wall, and then make a nice frame to cover the gaps thereafter.

Excellent solution. Now you also future-proof👍

Show us images when you done, for the benefit of others that also need to address legacy issues.
