FAQ
ACB Shorting B contact (SBC)
Why is the "shorting b-contact" (SBC) needed?
Answer
This contact(SBC) is used to auxiliary switch(AXb) contact. When Drawout type ACB is moved from "test" position to "disconnect" position, AXb contact will be disconnected by ACB position. Thus, Shorting b-contact (SBC) keeps AXb "connecting" state electrically. SBC can maintain the external control circuit even ACB is disconnected.
