Posted March 14, 20232 yr 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?

March 14, 20232 yr 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.

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

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.
March 14, 20232 yr 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.

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.
March 16, 20232 yr Author 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. Edited March 16, 20232 yr by BritishRacingGreen
