The box terminal as a factory-assembled connection can be optionally selected as an
alternative to the nut keeper kit (see chapter Front busbar and cable lug connections
(Page 232)) for all 3VA molded case circuit breakers up to size 160 A. The 3VA breaker is
then shipped with preassembled box terminals.
An auxiliary connection can be implemented using a special control wire tap. For further
information, please refer to chapter Auxiliary conductor terminal (Page 269).
In addition to directly connected cables, flexible busbars can also be connected to box
terminals.
The tables below show all the types and sizes of cable and flexible busbar that can be
connected to a box terminal.
