Front connection bars extended
Front connection bars extended can be installed to connect larger busbars and cable lugs
outside the termination area of a 3VA molded case circuit breaker. The front connection bars
therefore extend the jumper lug of the breaker.
All front connection bars extended are supplied as standard with phase barriers to provide
insulation between individual phases (see chapter Insulating equipment (Page 191)).
A special terminal can be installed to provide an auxiliary conductor connection. For further
information, please refer to chapter Auxiliary conductor terminal (Page 199).
The table below provides an overview of the minimum and maximum sizes of cables and
busbars which can be connected by front connection bars extended.
