Hi,

We have couple broken circuit breaker from ABB. It's my first time working with a broken circuit breaker. It's installed in training workbench power unit.

It's pretty expensive, I wonder if I can fix it ?

I screwed out the whole unit and took out this CB. Then I tried to open it from the front but couldn't. I was able to only open it from behind which is the part containing springs and metal contacts.
