Can anyone help me out with a internal circuit diagram for ABB HPA circuit breakers.
I'm not having much joy from ABB or its website on this one.
Your help would be much appreciated
I have attended a couple of courses over the last couple of years. In Vassa finland at ABB and their University in Basden Switzerland. I found them to be very good but they were definatly not for beginners and of course were only specific to ABB relays.
They try and give specific training...
