Braking Resistor Circuit With a Thermal Fuse.
Shown below is the connection diagram using an MCCB with a Trip Coil (TC) in lieu of an input
contactor. A control transformer is required for 400-volt models only. The primary MC is opened
in the event of a DBR over-current detection. With no power supplied to the ASD, the failure will
not be displayed on the EOI; see the Trip History for failure information once restarted.
