Front connection bars broadened
Front connection bars broadened can be installed to connect very large busbars and cable
lugs outside the termination area of a 3VA molded case circuit breaker. Front connection
bars broadened increase the distance between pole centers of the jumper lugs of the molded
case circuit breaker.
All front connection bars broadened 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 broadened.
