Are these the oldest rcbos?

[VanSolo]

Found some of these while doing a PIR. Does anyone know if they are the oldest rcbos? They seem to have been fitted in the early 70s.and take up two and a half ways in the board. The only ones I can think of that are near that old are the square d qo ones.

Sorry about the picture quality. It's from my old phone (which I had to charge especially)

Hows about a crabtree C50 RCBO?

 

[VanSolo]

I hated the terminals on those things
and you had to fit your own neutral flylead if i'm not mistaken.

I haven't got a picture, But I've removed some federal stablock RCBOs (of the older black bakelite type that look similar to the C50 range)

I'm not even sure you can class them as an RCBO as they are 2 separate units that clip together like a shunt trip??

we still have a few C50s at work.

they all still check out fine, even if a few do trip a bit prematurely for overload at times, they are in use for the stage lighting.

a bit OT, but is there a direct replacement for them, or would it be a new distro?

Soon after though the Vigi became all one unit two module size, still known as a C45 before being replaced by the C60.
Used extensively in petrol stations due to the D/Pole

You can still get the mcb's new, not sure about the rcd's

are they Merlin Gerins?

we have tons and tons of them at work and still fit the newer versions now

 

[VanSolo]

Yes they are Merlin Gerin, they have the old MG logo to the left of the mcb part
