alternative to the lug terminal (see chapter Front busbar and cable lug connections
(Page 181)) for all 3VA molded case circuit breakers up to size 160A. The 3VA breaker is
then shipped with preassembled box terminals.
A special terminal can be installed to provide an auxiliary conductor connection. For further
information, please refer to chapter Auxiliary conductor terminal (Page 199).
In addition to directly connected cables, flexible busbars can also be connected to box
terminals.
