Replacement breaker help.

1.6K Posts

I am trying to buy a replacement breaker. Without unscrewing the current fuse box and taking out the current one, I wanted to know if anyone can advise if this is a match?
The only difference I see is a 2 in the bottom corner, rather than a 1 in the top? Not sure what that means.
I need a 20amp breaker.

You need a 6amp MCB, the one pictured is 20amp. Otherwise it looks like the right type.

The one shown should be a direct replacement. I understand the 'B' before the rating number indicates a 'type' - how fast it responds, like the slow & fast-blow fuses you can get. Not sure which way.
If it breaks, well it wasn't working right anyway.
Good luck!
